[Zope-dev] [BUG] Python 2.1.2 & Zope 2.4.1

Hi, I decided to upgrade my Python 2.1.1 to Python 2.1.2 (in order to gently move to 2.5 later). My Zope instances were working quite fine....but...randomly I got a core dump (!) and the following message in logs : assertion "STACK_LEVEL() <= f->f_stacksize" failed: file "Python/ceval.c", line 687 Bug seems to appear when playing with ZCatalog (CMF sites could'nt even render a page) and Python scripts ? After some hours of researches, I have a (dirty, really) fix : I had to modify Python sources and hack line 687 in ceval.c : I removed it... Then recompile and it seems to work. I know this is dirty, and my Zope my crash later. PLEASE CHECK and HELP ! This looks like a major serious bug to me. Cheers, Olivier.
