Status: Open
Bug Type: Reproducible crash
Operating system: FreeBSD, Linux, ...
PHP Version: 4.0.5
Description: session_encode() crashes when there's data to encode
After glancing at ext/session/session.c and testing some more: Things work fine if I
set register_globals on. Pretty obviously a workaround I'd like to avoid.

Here's a backtrace. Hoppefully this submit form doesn't mess it up beyond repair.

I'm testing some user session handling now, and have found a reproducible crash. The
following page causes a crash:
<?php
include('dummysessionhandlers.inc.php');
session_register('foo');
session_encode();
?>
While the following code does _not_ crash:
<?php
inlude('dummysessionhandlers.inc.php');
session_encode();
session_register('foo');
?>
Relevant info from php.ini:
session.save_handler = user
session.serialize_handler = php
session.use_cookies = 1
session.use_trans_sid = 1
The "dummysessionhandlers" are all functions that just return true.
