openbox: debugging amd64 issues

[Pierre-Yves Ritschard <pierre-yves_(_at_)_spootnik_(_dot_)_org>]

Hi,

I'd like your input on where to search for issues in openbox.
This wm works great on my OpenBSD/i386 box and I'm pretty happy with it.
On OpenBSD/amd64 it has an erratic behavior, keeps crashing... it's not in a 
usable state.

gdb reports unauthorized memory access errors but since it doesn't happen on 
i386 i guess i should be looking for type size (64 != 32) issues.
Any obvious and common errors I should track, I'm starting to look through the 
source and might as well ask your advice.
