Description:
------------
When I call session_cache_expire() on Linux to get the current cache time (but not set it) I get this weird error message saying that a large amount of memory is being allocated. This does not reproduce on Windows but also appears on a separate Linux build server we have.

This scenario occurs with both unicode enabled and disabled.

Reproduce code:
---------------
<?php
var_dump(session_cache_expire());
?>

Expected result:
----------------
int(180)


Actual result:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 3067441245 bytes) in /mnt/hgfs/Projects/Session/php-6.0/Test.php on line 3

This weirdness also seems to affect session_cache_expire():

--TEST--
Test session_cache_expire() function : variation
--SKIPIF--
<?php include('skipif.inc'); ?>
--FILE--
<?php

ob_start();

/* 
 * Prototype : int session_cache_expire([int $new_cache_expire])
 * Description : Return current cache expire
 * Source code : ext/session/session.c 
 */

echo "*** Testing session_cache_expire() : variation ***\n";

ini_set("session.cache_expire", 360);
var_dump(session_cache_expire());
var_dump(session_cache_expire(999));
var_dump(session_cache_expire(180));
var_dump(session_start());
var_dump(session_cache_expire());
var_dump(session_destroy());
var_dump(session_cache_expire());

echo "Done";
ob_end_flush();
?>
--EXPECTF--
*** Testing session_cache_expire() : variation ***
int(360)
int(0)
int(999)
bool(true)
int(180)
bool(true)
int(0)
Done
