 [2009-01-09 10:21 UTC] karsten at typo3 dot org
Description:
------------
Two instances of SplObjectStorage should be considered equal only if 
they contain the same objects, when using == for comparison.

Reproduce code:
---------------
<?php
$someObject = new \stdClass();

$objectStorage = new \SplObjectStorage();
$objectStorage1 = new \SplObjectStorage();

var_dump($objectStorage === $objectStorage1); // FALSE, fine
var_dump($objectStorage == $objectStorage1); // TRUE, fine

$objectStorage->attach($someObject);

var_dump($objectStorage === $objectStorage1); // FALSE, fine
var_dump($objectStorage == $objectStorage1); // TRUE, huh?

$objectStorage1->attach($someObject);

var_dump($objectStorage === $objectStorage1); // FALSE, fine
var_dump($objectStorage == $objectStorage1); // TRUE, fine

?>


Expected result:
----------------
bool(false)
bool(true)
bool(false)
bool(false)
bool(false)
bool(true)


Actual result:
--------------
bool(false)
bool(true)
bool(false)
bool(true)
bool(false)
bool(true)
