From: [EMAIL PROTECTED]
Operating system: Redhat7.2
PHP version: 4.3.0
PHP Bug Type: Reproducible crash
Bug description: Apachi SAPI child segmentation fault in memset
Crash is 100% repeatable - script previously worked until I grabbed a
latest horde CVS update - tried recompiling binary etc, no dice
Other php scripts work correctly - not sure which command in the PHP
script is triggering the SIGSEGV
Setup:
apache_1.3.27
php-4.3.0
horde (CVS latest 12/30/2002)
imp (CVS latest 12/30/2002)
attempting horde/login.php
