You're saying if you stash the return value it runs fine, otherwise it 
crashes?  That sounds like some kind of messing up of the stack.

Is it possible you're doing extern(C) when you need to be doing 
extern(Window), or vice versa?

I don't have much experience with that so I'm just throwing it out. 
Maybe it just won't link if you get that wrong.
