So I'm assuming that it does neither occur with any of the
actively supported PHP versions[1].

Description:
------------
I use php-fpm + opcache.
My configuration is following:
opcache.enable=1
opcache.revalidate_freq=2
opcache.validate_timestamps=1
opcache.log_verbosity_level=4
When accessing test script twice, memory leaks detected.
I think this bug occurs when updating cache.
This leaks occurs on PHP 5.5(Git-2015-05-08), PHP 5.6(Git-2015-05-08).
But it does not occur on PHP 7.0(Git-2015-05-08)
Test script:
---------------
<?php
touch(__FILE__);
sleep(3);
Expected result:
----------------
Memory does not leak.
