Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php

This is a known problem caused by a call stack overflow.

Description:
------------
When calling a nonexistent method from __call or __callStatic, PHP crashes with 
the message "Segmentation Fault: 11"

Replicable in both PHP 5.3.18 and 5.4.8.

Test script:
---------------
class SegFault{
    public function __call($m, $a){
        $this->hjkl();
    }
}

$obj = new SegFault();
$obj->asdf();

--OR--

class SegFault{
    public static function __callStatic($m, $a){
        self::hjkl();
    }
}

SegFault::asdf();

Expected result:
----------------
I'd imagine a memory exhaustion error or the likes.

Actual result:
--------------
Segmentation fault: 11
