- downgrade worked great.  had to downgrade php4-common as well, and
there's an epoch (or whatever dpkg calls it) of 4:

sudo dpkg -i /var/cache/apt/archives/libapache2-mod-
php4_4%3a4.3.10-10ubuntu4.4_i386.deb
/var/cache/apt/archives/php4-common_4%3a4.3.10-10ubuntu4.4_i386.deb

The great news (in terms of a cause/effect) is that the sigsegv's went
away when I downgraded (and then ran ab to stress gallery) and they came
back when I re-upgraded to *4.5

All the error.log entries are the same (even when I modified the php.ini
settings and restarted.

[Fri Jul 21 17:44:07 2006] [notice] child pid 25320 exit signal
Segmentation fault (11)

Here are the errors-related entries in php.ini:

[EMAIL PROTECTED]:/% grep _errors /etc/php4/apache2/php.ini|grep -v ^\;
display_errors = On
display_startup_errors = On
log_errors = On
log_errors_max_len = 1024
ignore_repeated_errors = Off
track_errors = Off

Here's a later sigsegv that may be useful, although it is a potentially
corrupt stack.

How can install the symbols for this?  Or does it need to be a debug
version of the package (that hopefully someone else could build for me?)
