Description:
------------
This worked for quite a long time, but stopped working recently, I suspect due to 
#53971 being fixed. I think isset should never trigger any error

Test script:
---------------
$x = new stdClass;
$x->a = 'b';
var_dump(isset($x['a']));

Expected result:
----------------
false

Actual result:
--------------
PHP Fatal error:  Cannot use object of type stdClass as array in php shell code 
on line 1

It's not isset that's triggering this error.  The reason is that "$x['a']" is not 
valid when $x is an object.

Just for (cheap and lazy) regression purposes I tried this on PHP 5.2.17 and the 
same thing occurred so I don't think #53971 had anything to do with it.
