fprintf heap corruption

[arianc]

Hi
I have written a c++ code. It works well frequently but sometimes I see strange errors especially about out file streams. For example, this time I dealt with this messages:

'GABC.exe': Loaded 'G:\GABC\Debug\GABC.exe', Symbols loaded.
'GABC.exe': Loaded 'C:\WINDOWS\system32\ntdll.dll'
'GABC.exe': Loaded 'C:\WINDOWS\system32\kernel32.dll'

Heap corruption detected at 006131C0
The program '[3704] GABC.exe: Native' has exited with code 0 (0x0).

I have perceived that it is because of my "fprintf" command but I can't understand why this was working well before and also on Linux yet but now fails in XP. I would be grateful if anybody could help me.

Thanks

Well you'd need to post some code to get a better diagnosis.

Are you using windows 7 ? If yes, thats ur problem !
Windows 7 doesnt let you access system32 files through an external program!! Hence, Access violation reading location 0x00000038.
