Description:
------------
When dereferencing an object-reference in an array, php gets a segfault.

(see reproduce code)

Okay, I know that $object here is out of scope and should be subject to the GC, but PHP should still not segfault, but report an error or something like that. This bug makes horde-imp not work anymore on PHP 5 - the same code seems to have worked on PHP 4 (can't verify that, sorry).


Reproduce code:
---------------
<?php

class testobject
{
        var $test;
}

function return_object()
{
        $object = new testobject;
        $object->test = "lala";
        $array = array( &$object, NULL );

        return $array;
}

$object = return_object();
$object = $object[0]; // segmentation fault on this line

echo "WORKED: " . $object->test . "\n";

?>


Expected result:
----------------
The script prints out "WORKED: lala" or an error that the array-index is not present (or something like that).

Actual result:
--------------
(empty page, "[Mon Sep 20 12:45:01 2004] [notice] child pid 2075 exit signal Segmentation fault (11)" in apache-log)
