Description:
------------
 - Having an auto_prepend script encoded in UTF8
 - One regular page encoded in ASCII
 - A second page encoded in UTF8

(or the other way around)

Makes all the associative session variables unrecognized.

print_r($_SESSION) does out put the correct session variables. (the key is probably encoded differently which makes it not recognize it)



Reproduce code:
---------------
PREPEND FILE ENCODED IN UTF8 (no BOM) :

<?php
    $dummy = true;
?>

REGULAR FILE ENCODED IN ASCII :

<?php
    session_start();
    $_SESSION['foo'] = 42;

    include( <second page> );
?>

REGULAR FILE ENCODED IN UTF8 :

<?php
    echo $_SESSION['foo'];
    print_r($_SESSION);
?>


Expected result:
----------------
Display :
-----------------
42Array( [foo] => 42 )
-----------------

Actual result:
--------------
Display :
-----------------
Array( [foo] => 42 )
-----------------
