Description:
------------
Apache will crash session.serialize_handler is set to wddx and when a
$_SESSION var have the same name as a $_POST (or $_GET) var.
Try this code:
File w1.php
-----------
<?php
ini_set('session.serialize_handler', 'wddx');
session_start();
$_SESSION['a'] = 'test';
echo <<< EOS
<form action="w2.php" method="post">
<input type="text" name="a" value="">
<input type="submit">
</form>
EOS;
?>
File w2.php
-----------
<?php
ini_set('session.serialize_handler', 'wddx');
session_start();
print_r($_SESSION);
echo "<hr>";
print_r($_POST);
?>
