Description:
------------
Hello,

I'm using PHP 5.4.10 ts, 5.4.11 ts and 5.5Alpha1 ts.
I run PHP in CLI mode. (D:\localhost\php\php.exe -S 0.0.0.0:80 -t 
D:/localhost/htdocs -e -a)


Debugging: php5ts.dll!5fa2eb3389

Test script:
---------------
<?php
require_once("./function.php");
require_once("./libs/Smarty.class.php"); // http://www.smarty.net/

$data = "test";

$func = 1;

$smarty = new Smarty();
$smarty->assign('test', 	$data);

print_r(MyThreadFunc($func, $smarty));

?>

<?php
error_reporting(E_ALL);
class MyThread extends Thread
{
    public $func;
    public $data;
    public $res;
    public function __construct($func, $data)
    {
        $this->func = $func;
        $this->data = $data;
    }

    public function run()
    {
        //printf("%s is Thread #%lu\n", __CLASS__, $this->getThreadId());
        if($this->func == 1)
        {
            $this->res = func1($this->data);
        }
        elseif($this->func == 2)
        {
            $this->res = func2($this->data);
        }
        elseif($this->func == 3)
        {
            $this->res = func3($this->data);
        }
        elseif($this->func == 4)
        {
            $this->res = func4($this->data);
        }
        unset($this->data);

    }

}


function MyThreadFunc($func, $data)
{
    $t = microtime(true);
    $g = new MyThread($func, $data);
    /* starting synchronized */
    if($g->start())
    {
        printf("Request took %f seconds to start ", microtime(true)-$t);
        
        //while($g->isRunning())
        //{
        //    echo ".";
        //    usleep(100);
        //}
        if ($g->join())
        {
            printf(" and %f seconds to finish\n", microtime(true)-$t);
            return $g->res;
        }
        else
        {
            printf(" and %f seconds to failed\n", microtime(true)-$t);
        }
    }
    unset($data);
}


function func1($data)
{
	return $smarty->fetch('test.tpl');
}
function func2($data)
{
	return $data;
}
function func3($data)
{
	return $data;
}
function func4($data)
{
	return $data;
}

?>

Expected result:
----------------
The template test.tpl should displayed

Actual result:
--------------
Allow obj in Threads or build an error report
