Bug description:infinite loop in __tostring() causes seg fault
Description:
------------
The following piece of code would cause "PHP Fatal error: [php_fb]: call
depth has exceeded the maximum recursion setting of 500!, eject! eject!
eject!..." in 5.2.5. However, on versions 5.3.3 and 5.3.5, I am seeing a
segmentation fault.
Test script:
---------------
<?php
class A { public function __toString() { (string)$this; } }
(string)new A();
Expected result:
----------------
"PHP Fatal error: [php_fb]: call depth has exceeded the maximum recursion
setting of 500!, eject! eject! eject!..." seems a reasonable result.
Actual result:
--------------
segmentation fault
