Probally error occurs wher SOAPClient tried to parse zipped data in 
<data> tag or with CDATA section.

Does it use the stream zip format? Like what is available in java's soap or rpc?

Hmmmmm... I said wrong. Request is not zipped. It's CONTAINS zip in 
response. If you look in my response example U'll see an CDATA 
content with zip.

OK
I'll try to say more.

I try use standart SoapClient to work with SOAP service at 
http://portal.crog.ru/spo.asmx?WSDL with WS-Security and WS-
Addressing
with libraries
http://www.cdatazone.org/index.php?/pages/source.html

and use modified script from 
http://www.cdatazone.org/files/soap-wsa-example.phps

sources to reproduce error are here
http://sybro.com/capital.zip

php -f parse.php

When I call SOAP method GetSpoPartById 
I get segmentation fault on php5.2.6 under windows xp and linux 
debian etch

Let's see CapitalTourUpdater::getSpoByGuid()

...
public function getSpoByGuid( $guid )
{
// error produced here  - segmentation fault
// soapClient extended from SoapClient
 $response = $this->soapClient->GetSpoPartById( array('id'=>$guid) );
 var_dump( $response );
}


By the way SOAP method GetSpoCardLog calls normally
Let's see
CapitalTourUpdater::getUpdatedSpoGuids()
//normal executin of Soap call
$response = $this->soapClient->GetSpoCardLog($arrParameters_Query);

With HTTP sniffer I've seen that request goes to server, and server 
return valid response
As I write before response's example available at 
http://syabro.com/response.xml
