It appears that Wine isn't using Mesa's OpenGL 3.3 core profile yet:

> 0063:warn:wgl:is_extension_supported The function requires OpenGL version '4.3' while your drivers only provide '3.0'
> 0063:warn:wgl:wglGetProcAddress Extension GL_ARB_internalformat_query2 GL_VERSION_4_3 required for glGetInternalformati64v not supported

I don't know if GL_ARB_internalformat_query2 is the missing extension that is
causing the crash, but it does show that WoW is only able to use OpenGL 3.0
natively atm.
