Description:
------------
Hello,
The PHP interpreter crashes with "Segmentation fault: 11" if the __clone() function is
overriden to clone the object iself creating an infinite recursive call.
Test script:
---------------
<?php
class Crash {
public function __clone() {
return clone $this;
}
}
$crash_obj = new Crash();
clone $crash_obj;
Expected result:
----------------
The interpreter should suicide gracefully when hits the stack size limit.
Actual result:
--------------
Segmentation fault: 11
------------------------------------------------------------------------
