Description:
------------
I'm using the ISAPI filter in IIS6.
With register_long_arrays off, the session variables are not always saved.  

Note that in my example, I found that assigning $sv=$_SESSION; always breaks it, but my webpage only does assignments like $sv=$_SESSION['idx'] yet is still broken.

setting "register_long_arrays = On" in php.ini fixes the problem.

Reproduce code:
---------------
<head><title>test.php</title></head>
<html>
   <body>
      <?php
         session_start();
         $sv = $_SESSION;  //broken!
         //$sv['idx'] = $_SESSION['idx'];  //ok!

         if (isset($_SESSION['idx']))
            $i = $_SESSION['idx'] + 1;
         else
            $i = 0;

         $_SESSION['idx'] = $i;
         session_write_close();	
         echo '<p>SESSION START: '.$sv['idx'].'</p>';	
         echo '<p>SESSION END: '.$_SESSION['idx'].'</p>';	
      ?>
      <a href="test.php">test</a>
   </body>
</html>

Expected result:
----------------
SESSION START: n
SESSION END: n+1

(after clicking link)

SESSION START: n+1
SESSION END: n+2

Actual result:
--------------
SESSION START: n
SESSION END: n+1
(does not change even after clicking link. Note that older session data is kept, if idx=3 when requesting the test page, then n=3)

Hello,

I have the same problem on Linux. Calling 'session_write_close' with 'register_long_arrays = Off' in php.ini will save session data incomplete. With 'register_long_arrays = On' the data is saved completely.

Linux: 2.6.16
PHP: 5.2.0
Apache: 2.0.59

Reproduce code:
file: session.php
<?php

$systems = array();
$systems['sys1'] = array('par1' => 'val1', 'par2' => 'val2');

session_set_cookie_params ( 0 , '/' , '' , FALSE );
session_start();
setcookie( 'origin' , 'localhost' , 0 , '/' );

$_SESSION = array_merge( $systems , $_SESSION );

$_SESSION['user']['login'] = 'user02';

session_write_close();
var_dump($_SESSION);
echo '<a href="read_session.php">Continue</a>';
?>

file: read_sesssion.php
<?php

session_start();

var_dump($_SESSION);

?>


Session file bad
login|s:6:"user02";

Session file good
sys1|a:2:{s:4:"par1";s:4:"val1";s:4:"par2";s:4:"val2";}user|a:1:{s:5:"login";s:6:"user02";}
