Hi all,

i'm working on a big program, wich is an awful mix of C and C++. I'm
on windows XP, with Visual Studio 2008 SP1.
This program works fine in debug mode. But in release mode, there is a
crash without any message, and the catch() block don't catch nothing.

I located the function where the crash occurs. In this function, if i
add this code:

{
        std::cout << " *** 1 *** " << std::endl;
        vector<int> dum_vect( 520 );
        std::cout << " *** 2 *** " << std::endl;}

std::cout << " *** 3 *** " << std::endl;

the output is:

  *** 1 ***
  *** 2 ***
<crash>

That means that the crash occurs at the exit of the block, when the
vector is desalocated form the stack.
But why? And why there is no problem in debug, but only in release
mode?

You have an error on line 42 of your code.

That is, you have given us insufficent context to determine what your
problem may be.
Most likely it's stack corruption, caused by a buffer overflow. But
that's just a guess.
Please see FAQ 5.8 for further details on how to ask this question.
