Description:
------------
Apache 2.0.53 & mod_php5 5.0.3

Sessions occasionally work, but in two-thirds of the session requests
an error is generated and the apache child segfaults.

Error recorded in the logfile:

PHP Fatal error:  Unknown: Cannot find save handler \x02 in Unknown on
line 0

Error reported on site:

Notice: Undefined variable: HTTP_SESSION_VARS in <file>
Notice: Undefined variable: _SESSION in in <file>
Warning: session_register() [function.session-register]: Cannot find
save handler  in <file>
Warning: session_register() [function.session-register]: Cannot find
save handler  in <file>

I'm using php.ini-recommended as php.ini.

Tried commenting out session.save_handler, setting it to "files" and
just files.

Reproduce code:
---------------
session_start();
