Note the addresses there.

I'm not sure you can do that like that. lock.pBits is allocated with
HeapAlloc, and it looks like DIB_CreateDIBSection expects memory
allocated with VirtualAlloc, judging by a quick look at the code and
the commit comment here:
http://source.winehq.org/git/?p=wine.git;a=commitdiff;h=8b9f33851a5cfde1f812133603acb23128f2bd10
Perhaps someone a bit more familiar with that code could comment on
that.
