I dont think there is a relation. The following is what I found so far.
A backtrace from the crash with an wine with debuginfo intact:

The crash happens on reading address 0xb018cf0, which is an argument to the
StretchDIBits() call, so it comes from the application.

Exactly the same address appears when running this program in Windows under a
debugger. So the address is not the problem, but why it cannot be read in Wine
while apparently it can be in windows.

I am a bit stuck here, since the Windows debugger also reports that address  
cannot be read. The program seems to be able to do that just fine without
causing exceptions. 

Rein.
