Note that I posted this thread earlier, I'm reposting because the issue has evolved some and I have a clearer idea of what the problem is.

I'm trying to resolve a segmentation fault that occurs in the traversal of a string array. My code is doing the following:

- open a file
- read hex strings from binary file compiled from simple c++ program
- filter out any strings that are not 8 bits long (everything else is garbage)
- convert strings to decimal representation of hex string
- load decimal values into array to be used by Verilog module

The rest is erroneous.

Here is my code:

#include "VMIPS.h"
#include "VMIPS_MIPS.h"//required to explicitly access signals from submodules
#include <verilated.h> 
#include <stdio.h>
#include <cmath>
#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>
#include <cstdlib>
#include <vector>
using namespace std;

void outputLine( const string );
static inline int hexCharValue(char);

string array[274815];
unsigned int main_time = 0;
int i=0;
int k=0;//used for sorted array augmentation
int z = 0;//used for stream in counter
int main(int argc, char **argv) 
{
        //define local variables/arrays
        int temp;//hex conversaion accumulator
        string Hex;//dump variable for stream in
        
        //define objects
        ifstream inClientFile( "DAN_FILE.txt",ios::in );//stream in object
        Verilated::commandArgs(argc, argv);
	VMIPS *top = new VMIPS;
	top->CLK = 0;
        
        //popen();
        
        //test if instruction file can be opened
        if ( !inClientFile )
        {
            cerr << "File couldn't be opened" << endl;
            exit( 1 );
        }

        //fill string array with all file values and determines length of program
        while ( inClientFile >> Hex )
        {
            //fills array[..] with strings
            outputLine( Hex );
            i++;
        }

        z = i;
        cout << "Z:" << z << endl;
        int DataMem[z];
        int InstructionMemory[z];
        string tempInstructionMemory[z];

        //cut out undesired strings from array
        int u = 0;
        for(i=0;i<z;i++)
        {
                if ((array[i].length() == 8)&&((array[i].find("fs24")!=1)&&(array[i].find("f0")!=1)))
                {
                        tempInstructionMemory[k] = array[i];
                        k++;
                }
                else
                {
                     u++;   
                }
        }

        //convert string hex to numerical decimal
        for( int j=0;j<=z-u-1;j++ )//(z-u);j++ )//(z-u);j++ )//(z-u);j++ )
        {

So the issue seems to be occurring at line 77. This line converts string hex numbers to decimal integers. If one were to spell out this line (which is how I originally had done it.) the code would be the following:

if( tempInstructionMemory[j].at(y) ==  '0' ) temp = (0*pow(16.,(int)(7-y)));
else if( tempInstructionMemory[j].at(y) ==  '1' ) temp = (1*pow(16.,(int)(7-y)));
else if( tempInstructionMemory[j].at(y) ==  '2' ) temp = (2*pow(16.,(int)(7-y)));
else if( tempInstructionMemory[j].at(y) ==  '3' ) temp = (3*pow(16.,(int)(7-y)));
else if( tempInstructionMemory[j].at(y) ==  '4' ) temp = (4*pow(16.,(int)(7-y)));
else if( tempInstructionMemory[j].at(y) ==  '5' ) temp = (5*pow(16.,(int)(7-y)));
else if( tempInstructionMemory[j].at(y) ==  '6' ) temp = (6*pow(16.,(int)(7-y)));
else if( tempInstructionMemory[j].at(y) ==  '7' ) temp = (7*pow(16.,(int)(7-y)));
else if( tempInstructionMemory[j].at(y) ==  '8' ) temp = (8*pow(16.,(int)(7-y)));
else if( tempInstructionMemory[j].at(y) ==  '9' ) temp = (9*pow(16.,(int)(7-y)));
else if( tempInstructionMemory[j].at(y) ==  'a' ) temp = (10*pow(16.,(int)(7-y)));
else if( tempInstructionMemory[j].at(y) ==  'b' ) temp = (11*pow(16.,(int)(7-y)));
else if( tempInstructionMemory[j].at(y) ==  'c' ) temp = (12*pow(16.,(int)(7-y)));
else if( tempInstructionMemory[j].at(y) ==  'd' ) temp = (13*pow(16.,(int)(7-y)));
else if( tempInstructionMemory[j].at(y) ==  'e' ) temp = (14*pow(16.,(int)(7-y)));
else if( tempInstructionMemory[j].at(y) ==  'f' ) temp = (15*pow(16.,(int)(7-y)));
InstructionMemory[j]=InstructionMemory[j]+temp;

Now, if I comment out the lines 5 and 11 I no longer get the segfault. If I change the argument of the pow function to anything between 0-5 and 8+ then the seg fault doesn't occur either. Any ideas?

Line 46 says fills array with hex but you are not actually doing that. Could be your problem

As far as I understand my comment is correct. Could you elaborate please?

sorry did realize the array was global. I thought it was part of main.

Can you provide some test data set (the smaller the better) which exhibits the seg fault?

Here is a very small excerpt from the binary file hex dump that I'm reading.

>> which exhibits the seg fault

Are you sure a segfault is reproducible with this set?

I'm not positive about this segment causing an issue. First lets make sure that I posted the correct cpp. Here's the most up to date code and this definitely causes a seg fault:

Everything that handles syscalls and the MIPS object (verilator related things) can be commented out as it has no effect on this issue.

I don't get a segfault even with this sample. If you do, this would point to lines 57, 58, and 59. Switch to vectors, or at least use new int[z]

Thanks for taking a look at it. I'm going to run a few data subsets and see what happens. If I still get the fault I'll switch to vector.

It would really help if you could post the entire input file, that would allow us to debug the code and quickly find the remaining issues.

Of course, it would save yourself a lot of time in the future if you just learn on how to use the debugger yourself. It will tell you exactly at which point in the code the segmentation fault occurs and allows you to check the value of all variables to give you a hint why it occurred.

Other than the debugger, you can define _GLIBCXX_DEBUG for your project. This will alert you if any out-of-bound accesses happens in a standard container. However, that requires you to consequently use vectors instead of arrays, of course.

I'm having difficulty uploading the entire data file for some reason. It is 2.9MB so I'm not sure why. Regardless, I'm getting the same segfault for the samples I supplied. I'll re-post the most up to date code now, which is giving me a segfault right now, with the second sample I supplied.

I definitely should learn to use a debugger in this context. I'm used to using HI-TECH's compiler and debugger but that's a different world. What would you suggest? I'm working from a Mac and I'm compiling my program with Verilator (a Verilog/c++ interface compiler.)

The only reason why I'm really shying away from vectors is because I'm unfamiliar with them and I'm trying to do this relatively quickly. This isn't my field of expertise obviously (yet) so I'm dragging my feet a bit. Can you refer me to any good text references that outline and give examples of c++ code? I'm working from Deitel and Deitel at the moment.

I'm having difficulty uploading the entire data file for some reason. It is 2.9MB so I'm not sure why. Regardless, I'm getting the same segfault for the samples I supplied. I'll re-post the most up to date code now, which is giving me a segfault right now, with the second sample I supplied.

The sample doesn't cause a crash for me. It looks pretty weird, though. I mean, the RTF markup can't possibly be part of the real document, or can it?
To upload the file, just use some file hoster like Mediafire and delete it once this has been solved.

I definitely should learn to use a debugger in this context. I'm used to using HI-TECH's compiler and debugger but that's a different world. What would you suggest? I'm working from a Mac and I'm compiling my program with Verilator (a Verilog/c++ interface compiler.)

I assume the actual compiler used is g++. So gdb is the debugger you should use. Don't forget to add debug information when compiling (-g switch).

The only reason why I'm really shying away from vectors is because I'm unfamiliar with them and I'm trying to do this relatively quickly. This isn't my field of expertise obviously (yet) so I'm dragging my feet a bit. Can you refer me to any good text references that outline and give examples of c++ code? I'm working from Deitel and Deitel at the moment.

All you need to know about the standard library is on the reference on this site:
http://www.cplusplus.com/reference/stl/vector/

Still, a good C++ book should explain vectors shortly after the beginning.

I fixed up the code a bit. It's still not perfect... normally you would use iterators in the loops and a proper check whether a word is actually a valid hex string would be in order as well (edit: now taken care of).
Still, I'm pretty sure that the code cannot cause any segmentation faults anymore. I left the Verilated related code commented out and didn't touch it. If you still get segfaults, the problem is in there.

Some problems I saw when I went through the code:

1. You used InstructionMemory's elements, even though they were uninitialized. Elements of int vectors will be initialized to 0, but that does not apply to arrays.
2. You used various global variables without any reason. They didn't have any helpful names either. This severely limits readability. Variables should be defined as locally as possible for the same reason.
3. You used "z", a non-constant for your array sizes. This is not legal C++, even though it works with gcc.
4. You filtered out words with f0 at position 1, thus filtering some valid hex strings.

Edit: 5. ...and you included some stray strings on the right side of the file. Since there were a few spaces, some words there happened to have the length 8.
I now included a proper check and eliminated the now somewhat obsolete tempInstructionMemory.
Still, in theory valid hex strings could appear on the right side.

The seg fault is definitely gone. Thanks for sifting through my code and fixing it. I'm going to go through what you have changed in detail, I need to alter my code methodology significantly so I can get to this point when designing a new test-bench. DataMem is going to be implemented in the same exact way. InstructionMem is just a hypothetical storage element to supply my processor with instructions via PC addressing. The DataMem is the actual memory element (data cache) for the processor. Because I can disassemble the binary into these two segments I'll just dump instructions into one file, data into another and load them serially into my instruction and data vectors.
