Hmm.  Noteworthy is the large number of PHP extensions you have loaded, even
if you don't have any Zend extensions installed.  Could you try commenting
out any of these extensions not used by wordpress, and test whether that
affects your crash?

If it does, please uncomment the extensions one by one until the problem
shows up again, then send that list of extensions.  If it doesn't, please
send the minimum list of extensions that need to be enabled for your
wordpress instance to run.

In either case, it would be a good idea to try running apache under valgrind
to see if that permits pinning down the problem.

Alternatively, you may want to try the php version from etch to see if this
problem has resolved itself.
