Description:
------------
I am seeing the following backtrace in the memory plumber output which points 
that there is a memory leak with respect to tsrm_tls_entry in TSRM.c file:

==165== at  0x80395a890: __zend_realloc (php-5.3.25/Zend/zend_alloc.h:112)
==165== at  0x80395c7ef: _zend_hash_quick_add_or_update (php-
5.3.25/Zend/zend_hash.c:337)

==165== at  0x8038e6709: ts_resource_ex (php-5.3.25/TSRM/TSRM.c:361)
==165== at  0x8039e29f1: php_handler (php-
5.3.25/sapi/apache2handler/sapi_apache2.c:548)

I am using PHP 5.3.25 version. I looked for the patch release after this one 
that might have a fix for it, but I couldn't find one.
I would appreciate if you can throw some light on this memory leak to help me 
fix it. I cannot upgrade to new PHP version due to some inhouse roadblocks. 
However I can patch it to fix this memory leak.

Thanks in advance.

Actual result:
