Bug description:Memleak with static properties and internal/user classes
Description:
------------
There may occur memory leaks, if a user class extends an internal class
with
modified static properties:
â ~/build/php-5.4-dbg-zts-gcov$ sapi/cli/php -r
'http\Object::setDefaultErrorHandling(http\Object::EH_NORMAL);'
â ~/build/php-5.4-dbg-zts-gcov$ sapi/cli/php -r
'http\Object::setDefaultErrorHandling(http\Object::EH_NORMAL); class eh
extends
http\Object{}'

=== Total 1 memory leaks detected ===
http\Object::setDefaultErrorHandling() just does a
zend_update_static_property_long()
Test script:
---------------
<?php
http\Object::setDefaultErrorHandling(http\Object::EH_NORMAL);
class eh extends http\Object{}
Expected result:
----------------
<no output>
Actual result:
--------------
