Bug description: Serializing StdClass objects causes segfault
Description:
------------
Serializing StdClass objects causes segfault in PHP_5_0 but not in HEAD.
zend_std_get_method() (third stackframe) is called with __sleep as the
value for the method_name parameter so it looks like the serializer tries
to call a non-existant __sleep() method on the object.
Reproduce code:
---------------
<?php
print serialize(new StdClass);
?>
Expected result:
----------------
HEAD: O:8:"stdClass":0:{}
Actual result:
--------------
