Hi,

In one app I am porting code from jave to c++.The program compile fine but crashes when it enters into the ported code section.I use STL linked list implementation from here:

http://www.syncdata.it/stlce/stl_wce.zip

Java code:

```
LinkedList toProcessx;
LinkedList toProcessy;
void phaseUnwrap()
{
int startX = inputWidth / 2;
int startY = inputHeight / 2;
toProcessx = new LinkedList();
toProcessy = new LinkedList();
toProcessx.add(new int[]{startX});
toProcessy.add(new int[]{startY});
process[startX][startY] = false;
//println("StartX" + startX);
while (!toProcessx.isEmpty())
{
int[] x1 = (int[]) toProcessx.remove();
int[] y1 = (int[]) toProcessy.remove();
int x = x1[0];
int y = y1[0];
float r = phase[y][x];
if (y > 0)
phaseUnwrap(r, x, y-1);
if (y < inputHeight-1)
phaseUnwrap(r, x, y+1);
if (x > 0)
phaseUnwrap(r, x-1, y);
if (x < inputWidth-1)
phaseUnwrap(r, x+1, y);
}
}
void phaseUnwrap(float basePhase, int x, int y)
{
if(process[y][x])
{
float diff = phase[y][x] - (basePhase - (int) basePhase);
if (diff > .5)
diff--;
if (diff < -.5)
diff++;
phase[y][x] = basePhase + diff;
process[y][x] = false;
// toProcessx.add(new int[]{x});
// toProcessy.add(new int[]{y});
toProcessx.add(new int[]{x});
toProcessy.add(new int[]{y});
}
}
```

Ported C++ code using linked list STL library

```
int inputwidth = 480;
int inputheight = 640;
list<int> toProcessx;
list<int> toProcessy;
int startX = inputwidth / 2;
int startY = inputheight / 2;
void phaseUnwrap2(float basePhase, int x, int y)
{
if(process[y][x])
{
float diff = phase[y][x] - (basePhase - (int) basePhase);
if (diff > .5)
diff--;
if (diff < -.5)
diff++;
phase[y][x] = basePhase + diff;
process[y][x] = 0;//false;
//toProcess.add(new int[]{x, y});
toProcessx.push_back(x);
}
}
void phaseUnwrap(void)
{
toProcessx.push_back(startX);
toProcessy.push_back(startY);
process[startX][startY] = 0;//false;
//println("StartX" + startX);
while (!toProcessx.empty())
{
int *x1,*y1;
x1 = toProcessx.front;
y1 = toProcessx.front;
toProcessx.pop_front();
toProcessy.pop_front();
//int *y1 = toProcessy.front;
//int *y1 = toProcessx.remove(toProcessy.front);
//int xy[2];
int x = x1[0];
int y = y1[0];
float r = phase[y][x];
if (y > 0)
phaseUnwrap2(r, x, y-1);
if (y < inputheight-1)
phaseUnwrap2(r, x, y+1);
if (x > 0)
phaseUnwrap2(r, x-1, y);
if (x < inputwidth-1)
phaseUnwrap2(r, x+1, y);
printf("X = %d Y= %d\n",x,y);
toProcessx.push_back(x);
toProcessx.push_back(y);
}
}
```

Could some one please tell me what is going wrong?

Thanks in advance
