 I don't understand what does the above have to do with the object
_creation_. The stack trace here seems quite correct, the problem indicated
by debugger exception inside ntdll.dll is that you had corrupted the heap
somehow before. This often happens if you don't compile wx library and your
own code with the same CRT settings for example.
