I'm not sure what you're trying to achieve here since your reproduce script is just nonsense. Please provide a self-contained script that begins with '<?php' and ends with '?>' like a PHP scripts usually do.

Problem vanished when updated to 5.2.4, probably my old 5.2.3 was little buggy. Remove this submition, please.

I don't think there was any problem in 5.2.3 either..
