4.0..x does not raise error, but 4.1.x does.

<?php
error_reporting(E_ALL);
class testclass { var $dd = ""; }
$test = new testclass();
if (isset($test->dd[0])){
    echo "(A) TRUE \n";
}else{
    echo "(A) FALSE \n";
}
if (is_array($test->dd) && isset($test->dd[0])){
    echo "(B) TRUE \n";
}else{
    echo "(B) FALSE \n";
}
?>

Should be fixed before 4.2.0, IMO

There is nothing wrong here, it prints "PHP Notice:  Uninitialized string offset:  0 in - on line 5" for me, which it should.
