With CDB (a user mode dbgr on win) and symbol file of ntdll.dll, I
have got a more exact crash point:

(call stack)
Entry          Function                  Called at
0x7c98decf     ntdll!RtlDebugFreeHeap    0x7c96a5cb
0x7c9468b7     ntdll!RtlFreeHeapSlowly   0x7c9468a8
0x7c93043d     ntdll!RtlFreeHeap         0x77bfc2d8
               msvcrt!free               0x41cf70
               free                      free(p)
               operator delete           a_delete ptr;
               string::remove_spaces()  input_entry.remove_spaces

ntdll.dll should be mapped at the same va for user apps, so those hex
numbers could be useful. I am not familiar with win internals, so
maybe someone good at it could help guess the crash reason.
