I am trying to setup Exponential 3.3-4 on Red Hat 9, Apache 1.3, PHP 4.3.3 and PostgreSQL 7.3.4. When I enter the servername/username/password and click Next at the Database Initialization step of the setup wizard, I am sent back to the first step of the wizard.
Looking through my Apache logs, I found a segmentation fault. I do have PHPBB, Mad.Thought and Horde running on the same installation without problems. I do know that Exponential with MySQL will work on the same installation (but I don't like MySQL).
What can I do to fix the problem?
If you need more detail about my setup, I can post the output from phpinfo. Thanks.

please go through the whole Apache configuration, i most cases I've found Segmentation fault (11) being caused by a missconfigured VirtualHost or something. I've also read in many forums that this can be caused by bad physical memory, but I think you should check your configuration first.

I'd like to pump the significance of this post up a little cause I think there may be more to it.
I use Zend to develop in. Whenever I debug I regularily get segmentation faults exactly like that. The Zend guys never figured it out. I think they ended up thinking I was crazy ;-)
But it happens all the time and randomly. Both on Apache 1.3 and 2.0 (I've found 2.0 much more stable) Stepping through the debugger to find out what line or lines causes it comes to no avail as it happens in random places.

I do not have Exponential running in virtual host mode, but I do have virtual hosts. I have gone over my Apache configuration and I do not see anything wrong with it. Should I post my configuration?

Alright, here's another weird thing going on. I know the problem is with Exponential now. I have two computers: one at work and one at home. My original post refers to my home computer. My work computer runs Exponential on PostgreSQL just fine (except for a problem with module not found errors when I use the setup link class, but I'll save that problem for another post). My work computer runs the exact same software (Red Hat 9, Apache 1.3, PHP 4.3.3 and PostgreSQL 7.3.4) because I built the RPMS at home and brought them to work.
Anyways, I upgraded my work computer to Exponential 3.3-5. Now it gets segmentation faults. I reverted back to Exponential 3.3-4 and everything works again.
I will try diffing the two and see if I can fix this myself, but if anyone has any ideas on how to fix this, please share. Thanks.

Just an update. Whatever you guys did in 3.4 fixed the segmentation fault problem. Keep up the great work!
