So I guess this may be directly related to graphics after all? For the record, I also tested without mod_ssl and without mod_perl as well. Still segfaulted. I'm about to try 4.0.8-dev from snaps and see if that makes any difference. ------------------------------------------------------------------------ [2001-10-21 18:28:34] sniper@php.net I can't reproduce this with PHP 4.1.0Rc1 and GD 1.8.4.
