Description:
------------
While fuzzing PHP 7.0.0-dev (cli) (built: Jul 12 2015 03:27:06), I came across a script that causes a whole heap of trouble, most likely a buffer overflow of sorts, not sure how far the security implications go, but better safe than sorry, however, it doesn't appear to affect an older version such as PHP 5.4.41-0+deb7u1.

Test script:
---------------
<?php
class wp0{private$d;function __get($e){return$this;}}function ret_assoc(){}$wp0=new wp0;$wp0->i=&ret_assoc();

Expected result:
----------------
A graceful failure, easy to understand error message, obviously not this.

Actual result:
--------------

FYI, the unminimized version of this script causes some issues in PHP 5.4.41:

So no comment on the unminimized version of this test case crashes PHP 5.0.4, 5.0.5, 5.1.0 - 5.1.6,  5.4.0 - 5.5.26, 5.6.0 - 5.6.10? Should I open a new bug for those? Seems like it might be important.

PHP 5.5 and below are in sec-fixes only mode. I fixed the bug in PHP 5.6 though; just didn't seem to be auto-added here:
