When giving variable variable argument to isset() it is not checking correctly.
It was working property with the snap from 21 February (and of course works correctly with php 5.2 branch).

$var_name = 'unexisting';
if(isset($$var_name))
    {
    print $$var_name;
    }
?>

Expected result:

//print nothing

Actual result:

Notice: Undefined variable: unexisting in /home/local/test/t3.php on line 5
