Demo program

If SDL_CreateTexture() takes the !IsSupportedFormat() path it will return a SDL_Texture* with a NULL driverdata member.

If you then SDL_GL_BindTexture() this will cause a segfault in GL_BindTexture() when it unconditionally dereferences driverdata.

Debian Wheezy, binary Radeon drivers on a "AMD Radeon HD 6900 Series".
