I don't know excatly, but when I compile a program in debug mode, msvc
fills the memory with 0xcd (and when it's deleted it gets filled with
0xcc or 0xdd - have to take a look into msdn...) - and that's the real
problem. Maybe in release it get filled with 0x00 but who knows and
therefore it should be initilaized correct by the programmer.
And it looks like gcc/mingw initialize it with zeros too - Ralf Habacker
wrote some code for qt3/free which did not work for me because he was
using gcc with unitialized variables and I with msvc got crashes...
