Description:
------------
when run 5.4+APC with USE_ZEND_ALLOC=0

valgrind complain mem leaks

plz note I run the test script in this way:

$USE_ZEND_ALLOC=0 valgrind --leak-check=full php54 -S `hostname`:8964 

and the test script should be index.php

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

$there = 'world';

class hello
{
    function __construct($p)
    {   
        $this->testme($p);
    }   

    function testme($p)
    {   
        echo "testme $p <br>";
    }   
}

$h = new hello($there);

Expected result:
----------------
no mem leak

Actual result:
--------------

The bug seems to happen only when phar is present, debugging without phar gives 
no errors. Need on further investigation.

the php is built without ZTS,  why there comes a "apc_pthreadmutex_create" ? :)

[2012-03-14 09:17 UTC] pajoye@php.net

@laruence 
This is for the locking mechanism in APC, nothing to do with TSRM or such. The 
cache memory management requires it, an entry could be concurrently updated.

Most of these leaks was pushed away and caused crashes, so they had to come back. 
Many leaks in APC are intentional due to the nature of how Apache or another SAPI 
works. Leaks in CLI might be OK for Apache and there's really no consent. For this 
reason I don't see why to leave this ticket open.
