returns 0xc0000000 on your "Win8.1 64bit 16GB RAM, GTX970 4GB VRAM ver361.43"
for DDSCAPS_TEXTURE | DDSCAPS_VIDEOMEMORY | DDSCAPS_LOCALVIDMEM. So it seems
that this is the same crash as on Wine.

This workaround works on Wine as well.

The amount of video memory returned by GetAvailableVidMem() could be
potentially limited to INT_MAX. However, this is not how native ddraw works so
I doubt such change would be accepted in Wine.
