Bug 125476

PHP seg faults whenever I run a command line script, no matter what the script
is. It seems to properly execute everything in the script and just crashes when
it finishes up. I'm also using mod_php with Apache to serve MediaWiki on this
same machine, and that seems to work just fine as well. It's just the PHP CLI
that appears to have trouble. Here is a backtrace from gdb of the core file 
created:

I don't know how useful this will be since PHP was not built with debugging
symbols. If I reinstall the port with WITH_DEBUG=true, strangely enough the
problem goes away--the PHP CLI no longer crashes.

How-To-Repeat: Even a very simple script can trigger this. For example:

snb@wiki1> cat foo.php
<?php echo "hello world\n"; ?>
snb@wiki1> php foo.php
hello world
zsh: segmentation fault (core dumped)  php foo.php
