Hello,

I've successfully installed Roundcube 0.4.2 on Solaris 10.
I'm running :
Apache 2.2.11
PHP 5.2.14
Mysql  Ver 14.14 Distrib 5.1.30
On the same server I'm running Squirremail.
But when I tried to login from the Roundcube start page, Apache crashed:

Apache log file:
==========
[Mon Oct 11 18:34:18 2010] [notice] child pid 18250 exit signal Segmentation fault (11),possible coredump in /tmp

Then I tried to debug the Apache, what I've before the crash is :

================================================
There is no error in the Roundcube logfile : /var/opt/roundcubemail-0.4.2/logs
I tried to debug the core file created by Apache:
================================

gdb httpd /tmp/core
Core was generated by `/opt/webstack/apache2/2.2/bin/httpd -D 32bit -f /etc/opt/webstack/apache2/2.2/h'.

        __orig_bailout = (sigjmp_buf *) 0x0
====================================
The Apache is working correctly with other virtual host, it's crashing only for the host using Roundcube.
I've tried Roundcube version 4.0, and PHP 5.3.3, I've got the same result (Apache child process crashing).

Any help would be appreciated.
