Description:
------------
While loading any script in the cli with opcache enabled a memory dump::

# php prueba

hello world*** glibc detected *** php: double free or corruption (!prev): 0x00000000017df930 ***

I know that opcache is making the conflict because if I comment the
/etc/php5/mods-available/opcache.ini
Everything works fine

Test script:
---------------
<?php

echo "hello world";

?>



Expected result:
----------------
hello world

without the glibc error

Actual result:
--------------
# php prueba

hello world*** glibc detected *** php: double free or corruption (!prev): 0x00000000017df930 ***
