I'm marking this one as closed. It appears that the problem was in
apache, not php. It looks like a couple of recent glibc rpm updates
were the source of the problem. After rebuilding apache and php I
haven't seen a seg faults in over 16 hours. Perviously I was seeing
5-10 per hour.
Thank you to those of you who took the time to help me with this
problem.

AHA! I just checked the script (and all of it's includes). There is
only one putenv call in the entire forum system. Perhaps these code
snippets can provide some insight (I'm going to see if I can crash the
server with a short script containing these functions).
//included from a conf file
$SERVER_TZ = "America/New_York";
// the potential offending code
function set_tz($timezone)
{
if( $timezone ) @putenv("TZ=".$timezone);
}
// one of the fields in users is time_zone. All users are currently
set to "America/New_York"
function get_user_by_id($id)
{
qobj("SELECT * FROM fud2_users WHERE id=".$id, $this);
if( empty($this->id) ) return;
return $this->id;
}
// within this init function the set_tz function is called
function init_user()
{
$s = new fud_session;
$u = new fud_user;
$s->cookie_get_session();
if ( $s->user_id && $s->user_id<2000000000 ) {
if ( !$u->get_user_by_id($s->user_id) ) {
$u=NULL;
$s->delete_session();
}
/* else NOP */
}
else $u = NULL;
if ( empty($u) && empty($s->id) ) $s->save_session();
$rv[0] = $s;
if( !empty($u) ) {
set_tz($u->time_zone);
define('d_thread_view',
(($GLOBALS['TREE_THREADS_ENABLE']=='N'||$u->default_view=='msg'||$u->default_view=='tree_msg')?'msg':'tree'));
define('t_thread_view',
(($GLOBALS['TREE_THREADS_ENABLE']=='N'||$u->default_view=='msg'||$u->default_view=='msg_tree')?'thread':'threadt'));
q("UPDATE fud2_users SET
last_visit=".__request_timestamp__." WHERE id=".$u->id);
$rv[1] = $u;
}else {
set_tz($GLOBALS["SERVER_TZ"]);
define('d_thread_view',
(($GLOBALS['TREE_THREADS_ENABLE']=='N'||$GLOBALS['DEFAULT_THREAD_VIEW']=='msg'||$GLOBALS['DEFAULT_THREAD_VIEW']=='tree_msg')?'msg':'tree'));
define('t_thread_view',
(($GLOBALS['TREE_THREADS_ENABLE']=='N'||$GLOBALS['DEFAULT_THREAD_VIEW']=='msg'||$GLOBALS['DEFAULT_THREAD_VIEW']=='msg_tree')?'thread':'threadt'));
$rv[1] = NULL;
if( !empty($GLOBALS["rid"]) &&
empty($GLOBALS["HTTP_COOKIE_VARS"]["frm_referer_id"]) )
set_referer_cookie($GLOBALS["rid"]);
}
define('s', $s->ses_id);
define('_rsid', 'rid='.$u->id.'&S='.s);
define('_rsidl', 'rid='.$u->id.'&S='.s);
define('_hs', '<input type="hidden" name="S" value="'.s.'">');
define('_uid', (($u->email_conf == 'Y')?$u->id:0));
return $rv;
}

I tried the cvs snapshot and I'm still seeing the seg faults. Is it
possible that Apache is the problem here and not PHP? In other words,
is the putenv setting with an enviroment variable for PHP or all of
httpd?

Please try using this CVS snapshot:
http://snaps.php.net/php4-STABLE-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php4-win32-STABLE-latest.zip
There have been couple of dozen fixes that might have
also fixed this. So please give the snapshot a go.

It looks like putenv() is the last thing called from PHP
land before the crash, so that's a start.
