Logged In: YES user_id=31435 Note that the patch is out of date. I agree the invariant you deduced should hold, but in fact it doesn't now, at least due to insane initialization problems in exceptions.c: http://mail.python.org/pipermail/python-dev/2006-May/065248.html I'd like to ensure & exploit a stronger invariant: http://mail.python.org/pipermail/python-dev/2006-May/065231.html but that's stuck for now. I put my work in progress on a new branch: svn+ssh://svn.python.org/python/branches/tim-exc_sanity BTW, I don't agree that the incref on Py_None wasn't needed. Py_None is getting assigned to two new pointers (tstate->exc_type and frame->f_exc_type), so should be incremented twice.
