I'm not an assembly guru bt this sounds very similar as the issue in Populous.
In that case the game used Lock directly and it played with the stack pointer
internally which messed up our own logic.

You might be able to get a nicer result using winedbg if you disable 'first
chance exceptions' (this are the DIBSection segfaults). See
http://wiki.winehq.org/Backtraces.

What mostly interests me is where the calls originate from. Is it from Wine
itself or from the game?
