New Comment:
The segfault seems to be happening in this included file that
re-configures the session handler.. I successfully had it output
working code until it includes this file, it fails at the
"Session_start" function:
<?php
// DAO
require_once "DAO_Session.php";
$DAO_Session =& new DAO_Session();
session_set_save_handler( array(& $DAO_Session, "dao_open"),
array(& $DAO_Session, "dao_close"),
array(& $DAO_Session, "dao_read"),
array(& $DAO_Session, "dao_write"),
array(& $DAO_Session, "dao_destroy"),
array(& $DAO_Session, "dao_gc"));
// I get output here;
// Fire up
session_start();
// segfault here: tail /apache/logs/error_log
/*

echo "here:" . date("Y-m-d H:i:s"); die;
class DAO_Session {
// functions here.. can post if requested
}

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide
an URL to it here. Try avoid embedding huge scripts into the report.

Description:
------------
I've just attempted to upgrade to 4.3.10 and apache is segfaulting when
trying to load up the same application (custom) that runs on 4.3.9.
Setup: apache 1.3.33
php 4.3.10
[configure command]
./configure --with-apache=../apache_1.3.33
--with-config-file-path=/apache --enable-ftp --with-gd --with-mysql
--without-pear --enable-sockets --with-zlib-dir=/usr/include/
--with-freetype-dir=/usr/local/include/freetype2/ --with-openssl
Expected result:
----------------
Application should load as it does in 4.3.9.
Actual result:
--------------
I ran a gdb trace below:
(gdb) file /apache/bin/httpd
Reading symbols from /apache/bin/httpd...(no debugging symbols
found)...done.
(gdb) run -X -DSSL
Starting program: /apache/bin/httpd -X -DSSL
(no debugging symbols found)...
Program received signal SIGSEGV, Segmentation fault.
