PHP Segfault-ing: Preg_replace

| Comments

Update: issue now fixed.

ARGH! I cannot yet figure this one out. This code segfaults (gives memory allocation errors to) my copy of PHP, and also that on simplepie.org, but not that at php5.simplepie.org (the dev server). So there must be a difference in the PHP compilation/dependencies (as I am told that the versions of PHP are the same).

And yes, the & stuff is deliberate.

This is really frustrating. Ideas, anyone?
