[Kalzium] Crash on x86_64 while the code works on 32bit systems

[Nicolas barnier]

Hi Carsten,

FaCiLe works great on our 64 bits machine and I don't see any FaCiLe 
related code
in your snippet, so it seems that your problem might rather come from 
the C/OCaml
interface code. I would suggest to fill in a form in the OCaml bug 
tracking system
http://caml.inria.fr/mantis/view_all_bug_page.php providing enough code 
so that
the Caml team will be able to reproduce your bug - you might even be 
able to remove
any call to FaCiLe to reduce the size of the code and still get the seg 
fault within
the C/OCaml stub-code.

Thank you for your interest in FaCiLe
