Description:
------------
Same problems (segfault) with second call on same client object (re-opening SoapClient solves this issue)

Similar problems as described here: #35570


Reproduce code:
---------------
$c = new SoapClient('api_v0.2.wsdl', array(
	'encoding'   => 'UTF-8', 
	'trace'      => true,
	'exceptions' => true,
));

// call 1  --> OK
// call 2  --> segfault

Expected result:
----------------
Both calls ok, no segfault

Actual result:
--------------
PHP Warning:
Warning: SoapClient::__doRequest(): 31 bytes of buffered data lost during stream conversion! 

Segmentation fault

Tried with the latest PHP (from the link you gave me) - still no luck

PHP: 5.2.4 and 5.2.6

SOAP Server Example -------:
<?
function myMethod($user, $pwd)
{
  $rslt = str_repeat('x', 7444);
  return $rslt;
}

ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache
$server = new SoapServer("http://myURL/my.wsdl");
$server->addFunction("myMethod");
?>

SOAP Client test code -------:

<?php
ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache -- remove after testing
$client = new SoapClient("http://myURL/my.wsdl");
try
{
        print($client->myMethod("asdf", "asdf"));
        print($client->myMethod("asdf", "asdf"));
}
catch (SoapFault $exception)
{
        echo $exception;
}
?>


Attempting to return a string 7443 X's succeeds.  7444 fails with message: PHP Warning:  SoapClient::__doRequest(): 1 bytes of buffered data lost during stream conversion!.  After failure, a second SOAP invocation results in a segmentation fault.

FWIW: Hitting the same SOAP server with a VBScript test script doesn't exhibit the error.

PHP 5.2.6;  CentoOS5 and Ubuntu 8.04
I have exactly the same problem on both machines.
I can send ~300 SoapClient requests, and when one of it results false (null) the followup one causes segFault (script crashes and stops)
Any news here?
