This doesn't really make sense to me - the point of unspecified behavior 
if a parameter is NULL would be to speed up the function under contract 
with the caller. If you're already doing the check, why not handle it in 
some way other than crashing?

Anyway, I'm not familiar with wine development practices, so I wouldn't 
know whether this is the right thing to do - just wanted to point it 
out. I also see the same thing done in other wined3d patches.
