In a filter_callback function, if the function return false, the system crash, the apache hange.

if return other things other than false, for example 'aaa',true,1, it works

Reproduce code:
function returnTrue($val){
    return true;

function returnFalse($val){
    return false;

var_dump(filter_var('aaaa', FILTER_CALLBACK, array("options"=>"returnTrue")));

var_dump(filter_var('aaaa', FILTER_CALLBACK, array("options"=>"returnFalse")));

Expected result:

Actual result:
nothing can see, because the system crashed

This bug was fixed in PHP 5.2.6RC1. Make sure the version used in your test. (see the php version)
I can't reproduce on PHP 5.2.6RC6-dev.
