Reproduceable crash / anomaly

Hello all, since shortly after the release of PHP4b3, I am able to repeatedly crash Apache with a statically linked PHP, or at least produce anomalies in delivering content. Unfortunately, I am not able to pack it into a small example, as the script I am experiencing problems with was already quite large when the bug was introduced into PHP. I am talking about phpChat (http://www.phpwizard.net/phpChat). Setting up this application with any recent version of PHP (newer than PHP4b3) will result in Apache to indefinitely eat up resources (both CPU and/or memory) or simply stop responding, even to new HTTP requests. If anybody would be willing to work on this, I'd be glad to assist in setting up a test environment. Till
