Well, I think I found the cause if not the cure. I posted a bug report yesterday about zLib (http://bugs.php.net/?id=20535) that seems to be the culprit for another crash. Since our output compression uses it as well, I tried turning output compression off. No more segfaults.
Unfortunately, I'll have to turn it back on and live with the segfaults for now until I find the problem with zLib 1.1.4. :( Luckily, I happen to have one string saved away that I know crashes it. Hopefully it will be enough to figure things out.
