This is present in 5.3 too using the old style session_set_save_handler().
Seems to be related to the zend_try in php_session_flush().

Description:
------------
The apache or the CLI reports an segmentation fault while trying to die() or to
exit() a script in the write method of a class which extends the SessionHandler
class.
Test script:
---------------
<?php
class session_handler extends SessionHandler
{
function close () {return true;}
function destroy ($a) {return true;}
function open ($a,$b) {return true;}
function gc ($a) {return true;}
function read ($a) {return "";}
function write ($a,$b) {die();}
}
session_set_save_handler(new session_handler);
session_start();
session_write_close(); # apache segfaults
print "never appears?";
Actual result:
--------------
Apache/cli segfaults
