Description:
------------
Using += or -= etc. operator to assign to an array using an object for a key crashes apache rather than giving an Illegal Offset Type warning. ++, -- and =n don't crash apache.

FYI, I Installed the PHP windows binaries

Configure Command 	cscript /nologo configure.js "--enable-snapshot-build" "--with-gd=shared"

Reproduce code:
---------------
<?php
class Foo {
}

$foo = new Foo();
$collection = array();

$collection[$foo] += 1; // crashes Apache 2.0.49 on Windows XP

?>

Expected result:
----------------
Warning: Illegal offset type in C:\work\msat\src\test\crashApache.php on line 8

Actual result:
--------------
Apache crashes:

from Apache error log:
