Description:
------------
This may (or may not) be the same as bug 45282.  I cannot tell from his post whether or 

I experience this error irregularly.  I think I am missing something from the error that is happening.




Reproduce code:
---------------
define('MSN_CONNECTION_URI','https://adcenterapi.microsoft.com/Api/Advertiser/V5.1/'); 

$opts = array('trace' => true,  'compression' => SOAP_COMPRESSION_ACCEPT | SOAP_COMPRESSION_GZIP);

$my_client = new SOAPClient(MSN_CONNECTION_URI . "Reporting/ReportingService.svc?wsdl", $opts); 

Expected result:
----------------
$my_client should be a valid SOAPClient (and it usually is).

Actual result:
--------------
SOAP-ERROR: Parsing Schema: element 'http://schemas.microsoft.com/2003/10/Serialization/:anyType' already defined
