Description:
------------
System:
Apache 2.0.58
PHP 5.1.4
Windows XP Pro SP2

PHP.ini changes: 
short_open_tag = On
upload_tmp_dir = C:\php\uploadtemp
session.save_path = "C:\php\sessions"

Problem:
Session variables not being passed.

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

if (isset($_POST['username'])) {
	$_SESSION = $_POST;
}

if ($_SESSION['username'] != "myuser" OR $_SESSION['password'] != "mypass") {
	print "<form enctype=\"multipart/form-data\" method=\"post\" action=\"".$_SERVER['PHP_SELF']."\">
	<input type=\"Text\" name=\"username\"><BR><input type=\"Password\" name=\"password\"><BR><input type=\"Submit\" value=\"Login\">
	</form>";
	die();
}

?>

You are logged in!<BR>
You will clear the $_SESSION variable by clicking 
<a href="<?=$_SERVER['PHP_SELF']?>">here</a>.

Expected result:
----------------
Once logged in, the page should look identical before and after clicking the link.

Actual result:
--------------
Once logged in, clicking the link requires you to login again because the $_SESSION variable is not being passed.
