That's my point. It doesn't work on all systems. It works on two of my systems, both running PHP 4.4.0. It doesn't work on 3 other systems I have access to test the reproduce code. I've listed the PHPinfo links and some systems specs of systems that pass the test and systems that don't pass the test. All of them are running PHP 4.4.0. I'd really appreciate if you could look into the issue with your indepth knowledge of PHP.
