Re: ITERATOR LIST CORRUPTED error

I've migrated from VS2003 to VS2005. The followign code does not work
anymore -it shows assertion. Here is the test program:

#include "stdafx.h"
#include <windows.h>
#include <hash_map>

int _tmain(int argc, _TCHAR* argv[])
{
    stdext::hash_map<DWORD_PTR, int> map;
    map[100] = 1; map[200] = 2; map[300] = 3;

    stdext::hash_map<DWORD_PTR, int>::iterator itr =
            map.find(100);

    map.erase(itr); // assertion here

    return 0;
}

The program works well (Debug configuation) until I turn on Full
Optimization (/0x) compiler option. In this case I receive assertion:
ITERATOR LIST CORRUPTED.
If I turn off optimization - there is no assertion.

What is the problem ?
