Description:
------------
I have a custom php session handler that interacts with a database via PEAR::DB.  I have set session.save_handler to user.  I have test this using both MySQL and MS SQL Server 2000 on the backend.  Running this code can kill one of the Apache process consistently.  The short version of what I am doing is I authenticate my app, stick a user object in the session using $_SESSION['user'] = &$userObj; Then later I try to get that object out of the session by using $userObj = &$_SESSION['user'].  

To get code that reproduces this go here:

Reproduce code:
---------------
http://www.tonybibbs.com/filemgmt/visit.php?lid=5

Expected result:
----------------
I would expect that on page 2 I would get an instance of the object out of the session Ok.

Session extension does not work with references. Don't use those and everything will be fine.

If it crashes, provide a SHORT example script (one php file),
max. 20 lines of code. (yes, you can make it shorter)
And/or a gdb backtrace.
