Hello Jani, We tried a simple test and ran php5.2.3 "clean", by disabling third party extensions, including APC. We still got the core dump and the back trace landed in exactly the same place in code. Now we'll try the other suggestion and build/install 5.2.4RC3 and see if that makes the problem go away. Thanks, -Shawn Previous Comments: ------------------------------------------------------------------------ [2007-08-29 20:42:12] [EMAIL PROTECTED] First I need to quote one line from the page you sent this report from: "Always disable any Zend or other 3rd party extensions (Turck MMCache, ionCube loader, Xdebug, APC) before submitting a *PHP* bug." Before you start disabling anything, install the latest CVS snapshot from here: http://snaps.php.net/php5.2-latest.tar.gz And then disable all 3rd party extensions (APC especially..). ------------------------------------------------------------------------ [2007-08-29 18:42:12] shawn at mbuzzy dot com Description: ------------ I am running: Apache 1.3.31 Php 5.2.3 -- built with following switches: './configure' '--prefix=/local/service/php' '--with-apxs=/local/service/apache/bin/apxs' '--with-mysql' '--with-mysqli=/usr/bin/mysql_config' '--with-config-file-path=/local/service/php' '--with-mcrypt' '--with-curl' '--with-pdo-mysql' APC 3.0.14 We are getting a SEGV/core dump from apache httpd. The dump is reproducible in the sense that it happens regularly at about 2-3 hour intervals and the core back-trace is landing in exactly the same spot every time. However, it is not always processing the same php, so it's difficult to give you a reproducible php script to try yourself. However I do have a back-trace that might help. It appears to always be in a state where it is trying to setup the php global hash environment.
