digest is down; suggestions welcome

[Justin Sherrill <justin@xxxxxxxxxxxxxxxxxx>]

I upgraded shiningsilence.com from 1.12.1 to 1.12.2 last night; since  
then, PHP applications crash.

The DragonFlyBSD Digest is run with WordPress, which is in PHP, so  
I'm having a bit of trouble posting anything.   I'm seeing a whole  
lot of this:

[Mon May 12 21:08:51 2008] [notice] child pid 61809 exit signal  
Segmentation fault (11)

I occasionally get something in PHP (squirrelmail) to run after a  
restart of Apache, but it will stop after a few page loads.  I've  
updated and rebuilt Apache and ap_php; I'm running out of ideas on  
what could cause this or how to troubleshoot - I don't see any core  
files being created.  Suggestions welcome.
