It appears that pajoye is correct; there is a convert_to_string call that messes all of this up.
I'm not exactly sure what to do; it seems a rewrite is necessary to fix this behavior and that
is beyond my current skill level. I could just bypass the convert_to_string call and special case
this bug but that seems like a really bad idea.

Keep in mind that the problem (if you pass booleans as well) is the string conversion happening
before the filter is called. Making all Boolean checks impossible.

Yes, passing null as the first argument seems to be broken too. Please note that there is a
difference between passing null and an object though: http://3v4l.org/oFCpE
Passing an object never worked correctly.

Description:
------------
---
From manual page: http://www.php.net/filter.filters.validate
---
FILTER_VALIDATE_BOOLEAN with the FILTER_NULL_ON_FAILURE flag return false if the first argument is
an object. According to the documentation it should be null.
Test script:
---------------
<?php
var_dump(filter_var(new \StdClass(), FILTER_VALIDATE_BOOLEAN, FILTER_NULL_ON_FAILURE));'
Expected result:
----------------
NULL
Actual result:
--------------
bool(false)
