Summary: 0001231: is_subclass_of throws NullPointerException
Description: PHP:

<?php
if (! is_subclass_of(true, "foobar")) {
    print "boolean is not a foobar\n";
}
?>

This throws a NullPointerException in Quercus and works fine in standalone PHP. (Might happen with types other than boolean too, but that's what caused the exception in my actual code.)
