PHP Bug Type: Reproducible crash
Bug description: reflective functions crash PHP when interfaces extend
themselves
Description:
------------
When a interface extends it's self, it will cause PHP to crash when
reflective language features such as instanceOf, is_a are used on objects
that implement the recursive interface.
Reproduce code:
---------------
<?php
interface RecurisiveFooFar extends RecurisiveFooFar {}
class A implements RecurisiveFooFar {}
$a = new A();
var_dump($a instanceOf A);
?>
Expected result:
----------------
Something like ...
Fatal Error: interface can not extend it's self on line __LINE__ in
__FILE__
Actual result:
--------------
PHP Crashes. Apache log shows this activity.
