Bug description: PHP doesn't decode cookies anymore when POST body grows large
Description:
------------
When the body of a POST request grows too large, PHP stops decoding
the passed-in cookies properly. Usually this results in a session
that is dropped (the user being logged out, etc.)
Reproduce code:
---------------
<?
session_start();
$FIELDS = 200;
?>
PHP Version: <b><?= phpversion() ?></b><br>
Cookies: <b><? print_r($_COOKIE);l ?></b><br>
Session ID: <b><?= session_id() ?></b><br>
<form method="post">
<input type="submit" value="Send">
<? for ($i = 0; $i < $FIELDS; $i++): ?>
<input type="text" name="field[$i]" value="<?= md5(microtime())
?>">
<? endfor ?>
</form>
Expected result:
----------------
Session id does not change between posts, cookies are displayed.
Actual result:
--------------
Depending on the setting of $FIELDS, PHP does or does not drop the
cookies and therefore the session.
On my setup, setting $FIELDS to 100 works fine and the session is
maintained, setting $FIELDS to 200 exhibits the behaviour mentioned.
