Description:
------------
PHP correctly shows a Warning, but also segfaults when executing the script. This should be fixed, or the Warning should be updated to a Fatal instead

7beta3 is the only version that has this problem as can be seen on http://3v4l.org/C9KDr

Test script:
---------------
<?php

class A {
	public static function __invoke()
    {
        echo __CLASS__;
    }
}

class B extends A {
}

$b = new B;

$b();

Expected result:
----------------
Warning: The magic method __invoke() must have public visibility and cannot be static in /in/C9KDr on line 4
A

Actual result:
--------------
Warning: The magic method __invoke() must have public visibility and cannot be static in /in/C9KDr on line 4
Process exited with code 139.
