Description:
------------
This error occures both in CLI and Apache PHP module. If I use SoapClient with client certificate I get segmentation fault. Soap call(s) and all the script logic behaves as expected, but during PHP shutdown there's segmentation fault occured.
I reproduced this on two workstations with the same Fedora Core 6 and tried PHP versions 5.2.6 - 5.2.11 and 5.2.current.

Reproduce code:
---------------
<?php
// Program requires client certificate (I can send the one)
try
{
	$soap = new SoapClient('https://host/soap/?wsdl', array(
		'exceptions' => 1,
		'wsdl_cache' => WSDL_CACHE_NONE,
		'local_cert' => dirname(__FILE__) . '/client-cert.pem',
		'passphrase' => 'piglet'
	));
	
	$res = $soap->userLogin(array('login' => 'bugonek', 'password' => md5('000'), 'save_session' => false));
	if ($res !== false && $res->errorCode == 0)
		echo "SID: {$res->sid}\n";
	else
		echo "Login error: {$res->errorMessage}\n";
}
catch (Exception $e)
{
	echo 'Exception [' . $e->getCode() . '] ' . $e->getMessage() . "\n";
}
?>

Expected result:
----------------
SID: 3092b3e454a6f4c9bb8ccab01adce34c (this value is generated at runtime and not exactly should be the one)

Actual result:
--------------
SID: 3092b3e454a6f4c9bb8ccab01adce34c
Segmentation fault (core dumped)
