This makes no sense, Are you reproducing it just with this posted test script?!

Description:
------------
If ArrayAccess is extended and then the subclass accessed using object notation
then unpredicatable results occur. In the test script below an undefined
variable $xyz is somehow referencing the ArrayObject subclass Foo.
The same result occurs on Linux systems.
This came to light when using an unitialised value in the Zend Framework
Zend_Registry class, although it is not limited to that.
Test script:
---------------
<?php
class Foo extends ArrayObject{
public function __construct(){
parent::__construct(array(), parent::ARRAY_AS_PROPS);
}
}
$f = new Foo;
$f->Foo['bar'] = 1;
var_dump($xyz['xyz']); # This should throw a warning then null??
?>
Expected result:
----------------
PHP Notice: Undefined index: Foo in C:\jirasource\ABC\sites\partners.rfp-gener
ator.com\web\test.html.php on line 8
