PHP & Zend crashing Apache

[El Reggae Dancer <reggaedancer@xxxxxxxxx>]

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:
------------------------------------------------------

[Fri Oct 22 15:03:18 2010]  Script:

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