Description:
------------
I receive a segfault when executing the code below.  If 
I change $stuff[0] to "Small", everything works fine.

Reproduce code:
---------------
<?php
$client = new SoapClient("http://aws-beta.amazon.com/AWSSchemas/AWSProductData/beta/US.wsdl");

$request->{"Operation"}="ItemLookup";
$request->{"ItemId"}="1565926102";
$stuff[0]="Medium";
$request->{"ResponseGroup"}=$stuff;

$ar->{"Request"}=$request;
$ar->{"SubscriptionId"}="18BJZ2XBVHZX80H4YCG2";


$ar=$client->ItemLookup($ar);
var_dump($ar);
?>

Expected result:
----------------
The variable ar dumped.

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