Array access 5.2 != 5.3

I have a piece of code:

$data = array();

$data['foo'] = 'tst';
$data['bar'] = array('asd');
$data['user'] = new stdClass();

var_dump(isset($data->foo));

Now i have executed the code on two environments.

First: 

PHP 5.2.6-1+lenny16 with Suhosin-Patch 0.9.6.2 (cli) (built: Feb  3 2012 08:19:55) 
Copyright (c) 1997-2008 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies
    with Xdebug v2.2.4, Copyright (c) 2002-2014, by Derick Rethan

Second:

PHP 5.3.2-1ubuntu4.24 with Suhosin-Patch (cli) (built: Apr  4 2014 02:25:37) 
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies
    with Xdebug v2.2.5, Copyright (c) 2002-2014, by Derick Rethans

On the first i got as result bool(true) but on the second bool(false). I've read the migration guide (php.net), but there was nothing to find about this behavior.

Can anyone explain me this behavior?

Note:

If i change the code to

var_dump(isset($data['foo']))

i get the same result on both.

As you can see here, the behaviour changed between 5.2.11 and 5.2.12. The release notes for 5.2.12 refer to bug #50255 isset() and empty() silently casts array to object having been fixed.

So, it was a bug in older versions.
