Description:
------------
I have problem with $GLOBALS while executing scripts via SOAP Service. Objects passed by reference is not set in $GLOBALS and cannot be used in other classes. The same code works perfectly if executed direct in browser.

Reproduce code:
---------------
client.php
----------------------------------------------
ini_set("soap.wsdl_cache_enabled", "0");
 $client = new SoapClient("test.wsdl", array('trace'=> 1, 'exceptions' => 0));
print $client->testGlobals();

--------------------------------------------
server.php
----------------------------------------------
function testGlobals() {
	global $TestClass1, $TestClass2;
	require_once 'inc.php';
	return $TestClass2->testvar2;
}
ini_set("soap.wsdl_cache_enabled", "0");
$server = new SoapServer("test.wsdl");
$server->addFunction("testGlobals");
$server->handle();

--------------------------------------------
inc.php
--------------------------------------------
require_once('TestClass1.class.php');
require_once('TestClass2.class.php');
$TestClass2 = new TestClass2();

-------------------------------------------
TestClass1.class.php
-------------------------------------------
class TestClass1 {

	public $testvar1;
	function TestClass1() {
		$this->testvar1 = 100;
	}
}

$TestClass1 = & new TestClass1();

---------------------------------------------
TestClass2.class.php
---------------------------------------------
class TestClass2 {

	public $testvar2;
	function TestClass2() {
		global $TestClass1;
		$this->testvar2 = $TestClass1->testvar1;
	}
}




Expected result:
----------------
I expect the value 100 to be returned by service. 

Actual result:
--------------
Nothing is returned. The reason is that in TestClass2 there is no $GLOBALS['TestClass1'] unless I pass $TestClass1 by value:
(last line of TestClass1.class.php):
$TestClass1 = new TestClass1();

What is wrong here?
