Yes, I did that also and it worked. I guess the problem is elsewhere and that this valarray use is not at cause. It seems that the memory is corrupted somewhere else before because when I insert those two lines before the array2d construction it crashes the same at the delete call:

char * Line_str = new char[10000];
delete Line_str;

Very weird... I guess I have to go step by step through the program to see if there's a problem somewhere... I don't understand though why this problem doesn't show up with VC6...

I know where the problems lies, this simple program crashes for me:

int main(int argc, char * argv[])
{
char * Line_str = new char[10000];
delete[] Line_str;

return 0;

..... the rest of my program ...
}

I have this dialog:

---------------------------

For information on how your program can cause an assertion
failure, see the Visual C++ documentation on asserts.

And here is the backtrace:

msvcr80d.dll!102527a6()
[Frames below may be incorrect and/or missing, no symbols loaded for msvcr80d.dll]

gnss_core.exe!main(int argc=5, char * * argv=0x00a55f20) Line 25 + 0x15 bytes C++

Could it be that it is because my program is linked to a library that uses mfc42?
