--- Comment #1 from Roderick Colenbrander thunderbird2k@gmail.com 2010-07-16 19:35:37 --- I don't think this warning is related to the crash. This particular OpenGL call was around years ago but I'm not aware of any driver support for it (the opengl headers don't contain the call).
The program is just detecting whether the function is around by loading it and we just return NULL because it wasn't found. This is allowed on Windows (checking the opengl extension list is cleaner).
I can't say what the issue is but it is likely something else.
