I can not reproduce this.
What is "diff -u" between the php.ini-dist and the php.ini you have?

Shortest script to produce the bug:
<?php
session_start();
$_SESSION['sname'] = $_POST['name'];
$_SESSION['spwd'] = $_POST['pwd'];
$sname = $_SESSION['sname'];
$spwd = $_SESSION['spwd'];
?>
If delete any of this 5 lines it does not happen.

Please provide a _short_ example script, without any html
stuff (if possible) and without any mysql stuff (which doesn't seem to
be related to the crash, according to that backtrace).
