While using Zope 2.7 with Python 2.4 we discovered some strange behaviour of the security machinery. I could track this down to some Zope code in cAccessControl.c where an Unauthorized exception is raised because of a call to PyIntFromLong(1) which returns NULL. What could be the reason that such a "stupid" call return NULL in a reproducable way?

Ugh. Part of the problem is that all of those calls are unchecked, Dang us. If they were checked, then, who knows, we might have gotten informative exceptions.

I'd say the first step should be to add checks.
