Noted. The support for dealing with foreign libraries is pretty weak 
right now. I'll look into this soon, as it seems pretty straightforward 
to add.

Unlikely, because Allegro has IMHO the *best* behaviour regarding 
calling conventions. Things will work unchanged with either stdcall or 
cdecl. That is what I would like CFFI to do, but that doesn't seem 
possible in the near future, unfortunately. So we will need to add a 
way to specify calling conventions.

It'd be nice if you could send a reproducible test case for that 
Allegro crash (the smaller the better :-)).

Thanks,
