#50474 [NEW]: spl_object_hash returns same value for different objects
From: php dot net at karlsruler dot de
Operating system: Windows 7
PHP version: 5.3SVN-2009-12-14 (snap)
PHP Bug Type: SPL related
Bug description: spl_object_hash returns same value for different objects
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"

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 nächsten
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:
--------------
