Description:
------------
the native php soapclient throws a soapfault when passing complex types to a soap-service on php5.3.1 whereas php5.2.6-soapclient works correctly.

both, 5.3.1 and 5.2.6 ran on same machine with same modules enabled and almost same config.

the soapserver provides a test method that accepts exactly one parameter of type TestUser (see below) and returns the modified test object. 

I've tested the soapserver with soapUI and checked the wdsl, it 100%ly valid.

But the client on php5.3.1 troubles. See the actual soap-request (php5.3.1 vs. php5.2.6) below.

I guess it's a parsing error, but i couldn't find any hint in the releasenotes and changelogs.



You can also reproduce the bug??? by using Zend_Soap_Client, since it uses the native one. 

Reproduce code:
---------------
<?php /* soap client*/
    class TestUser {
        public $intUserId = 0;
        public $strName   = '';
    }

    $objUser = new TestUser;
    $sc = new SoapClient('path_to_wsdl' , array(
        'classmap' => array (
            'TestUser' => 'TestUser'
        )
    ));
    var_dump( $sc->test($objUser) );
?>

<?php /* soap server method */
    /**
     * @param TestUser $objUser the test user
     * @return TestUser $objUser the test user
     * @soap
     */
    public function test( TestUser $objUser )
    {
        $objUser->intUserId = 123456789;
        $objUser->strName = 'somename';
        return $objUser;
    }
?>

Expected result:
----------------
the expacted service result:

object(TestUser)#3 (2) {
  ["intUserId"]=>
  int(123456789)
  ["strName"]=>
  string(8) "somename"
}

the expacted client-request :

...<SOAP-ENV:Body><ns1:test><objUser xsi:type="ns1:TestUser">...</objUser> ...



Actual result:
--------------
php5.3.1 =>
