Ok, I think the problem was I was stripping the binary before moving it
around. Try this:

Comments:
I think the '--enable-debug' didn't get accounted for.
Please try deleting config.cache and reconfigure/compile PHP again.
Then generate that gdb bactrace. Hopefully it will have more info in it.

I recently wanted to do socket based options with PHP4, so I downloaded PHP
4.0.5, compiled it fine. However when I attempted to run the Ex2 Socket
Example: Simple TCP/IP client located at
http://www.php.net/manual/en/ref.sockets.php PHP 4 core dumped:
../mysocket.cgi
X-Powered-By: PHP/4.0.5
Content-type: text/html
<h2>TCP/IP Connection</h2>
l core
Segmentation fault (core dumped)
I recompiled PHP4 with the --enable-debug ('./configure'
'--with-mysql=/usr/local/mysql' '--with-gd' '--with-zlib' '--with-png'
'--with-xml' '--enable-ftp' '--enable-sockets' '--enable-discard-path'
'--enable-debug') and analyzed the core:
