Visual Studio - Release: Oh looks like this works.

Visual Studio - Debug: It seems you have an error:
"MVP = P*V*M;"
Quickly checks release... wait..
"
MVP=P*V;
MVP=MVP*M;
"
Compiles Debug version... Hey it works!!! Closes application window.... Error _free_dbg(block...
WTF...
Tries again, closes the cmd window, rather than win32 window. No errors.

TL;DR Screw windows for debugging C/C++
