Description:
------------
A very simple soap client with a fairly complex WSDL file segfaults on __getTypes()

Code is below.  No GDB trace, but if this can't be replicated I can send one.

The output:
$ php -v
PHP 5.0.0RC2 (cgi) (built: May 17 2004 20:08:36)
Copyright (c) 1997-2004 The PHP Group

Reproduce code:
---------------
#!/usr/local/bin/php
<?php

ini_set("soap.wsdl_cache_enabled", 0);

$WSDL_URL = "http://www.ee.oulu.fi/~raewasch/mad-cpi-php-bug.wsdl";
$client = new SoapClient($WSDL_URL);

print_r($client->__getFunctions());
print_r($client->__getTypes());

?>

Expected result:
----------------
Not a segfault.

Actual result:
--------------
$ php soap-test.php 
Content-type: text/html
