Description:
------------
[sorry for my english]

the ReflectionClass cause a segmentation fault if the constructor of a class, calling his parent constructor, throws an exception

if i use the syntax:

$myInstance = new $class_name();

all is ok

Reproduce code:
---------------
class A {
	function __construct() {
		try	{
			$this->test();
		}	
		catch(Exception $e)	{
			throw $e;
		}
	}
	
	public function test() {
		if(0!=1) throw new Exception("ERROR",100);
	}
}

class B extends A { 
	function __construct() {
		try	{
			parent::__construct();
		}
		catch(Exception $e)	{
			throw $e;	
		}	
	}	
}

try
{
	$class_name = "B";
	
	$class = new ReflectionClass($class_name);
	if ($class->isInstantiable()) 
		$myInstance = $class->newInstance();
}
catch(Exception $ex)
{
	echo $ex->getMessage();
}

Expected result:
----------------
printing of:
ERROR

Actual result:
--------------
segmentation fault in apache 2
