Hello,
I've compiled PHP 5.3.3 with Zend.
Sometimes, my Apache 2.2.11 crashed and created a core dump (probably due to
the
Zend enabled in PHP).
OS : Solaris 10 10/09 s10x_u8wos_08a X86
Apache logfile:
---------------
[Mon Oct 25 13:11:47 2010] [notice] child pid 3485 exit signal Segmentation
fault (11)
possible coredump in /var/opt/webstack/apache2/2.2/logs
and the Apache log file is full of the following message:
------------------------------------------------------

Is this a PHP bug, or my PHP is not correctly compiled and installed ?
Any help would be appreciated.
