Bug description:__destruct loop segfaults
Description:
------------
A destruct loop segfaults due "KERN_PROTECTION_FAILURE".
Please add some sort of counter (until 1000 for example) to every
destructor to avoid segmentation faults.
____
It is not funny when someone thinks he has to produce endless core dumps...
Test script:
---------------
<?php
class getDestructed {
public function __destruct() {
new self;
}
}
$class = new getDestructed;
Expected result:
----------------
Fatal error: Allowed memory size of %ul bytes exhausted at
Zend/zend_execute.h:%s (tried to allocate %i bytes) in xxx on line 3
or some restriction by a counter
Actual result:
--------------
