Description:
------------
spl_object_hash returns the same hash sum for different objects. First I have to say, I'm using PHP 5.3.2dev, compiled with VC9:

System 	Windows NT CHRISTIAN-PC 6.1 build 7100 ((null)) i586
Build Date 	Dec 6 2009 20:47:34
Compiler 	MSVC9 (Visual C++ 2008)
Architecture 	x86
Configure Command 	cscript /nologo configure.js "--enable-snapshot-build" "--disable-isapi" "--enable-debug-pack" "--disable-isapi" "--with-pdo-oci=D:\php-sdk\oracle\instantclient10\sdk,shared" "--with-oci8=D:\php-sdk\oracle\instantclient10\sdk,shared" "--with-oci8-11g=D:\php-sdk\oracle\instantclient11\sdk,shared" "--with-enchant=shared"

Zend Extension Build 	API220090626,TS,VC9
PHP Extension Build 	API20090626,TS,VC9
Debug Build 	no
Thread Safety 	enabled 

this allows me using Imagick-Extension on Windows Systems.

I hope I'm not reporting stupid things (f.e. SPL not working on Windows 7 or VC9 or ..), but I would assume, that this should always return different values.

Reproduce code:
---------------
<?php
require "./init.php";

$header = new Text("Das ist mein erstes Layout.");
$header->getPadding()->set(5);
$footer = new Text(".. und das wars auch schon wieder.\nBis zum n?chsten Mal!");
$footer->getPadding()->set(5);

$layout = new Layout_Vertical();
$layout->add($header);
$layout->add($footer);

echo spl_object_hash($header), "<br />";
echo spl_object_hash($footer), "<br />";
echo spl_object_hash($layout), "<br />";
// exit;

$renderer = new Renderer_Imagick($layout);
echo $renderer->display();
?>

Expected result:
----------------
different hash sums

Actual result:
--------------
000000002bb405ee00000000344e0650
000000002bb405ec00000000344e0650
