Ok. Firstly, the division by zero occurs in your program, so the first
step is to recompile it with debugging symbols, to see where exactly
something is going wrong. Secondly, it happens right after a return from
user32. So my guess is that you call some function in user32.dll and use
some of the values returned. I'll assume it doesn't crash on native
windows, so there are two possibilities:
a) The function in wines user32.dll is misbehaving, and not returning
correct values. 
b) The function in wines user32.dll is behaving correctly, but different
from what you expected. Check the return values more carefully.
