PHP 5.2.1 crashing Apache/IIS...

Heads up! Installed the latest Win32 binaries of thread-safe PHP 5.2.1 on Win32 Apache and IIS. PHP started crashing (definitely PHP - php5ts.dll) when I went to access the MyProBB web forum. (Win32 Apache flat out crashes, IIS bails with HTTP 500 errors). Forum crashes PHP 5.2.1: http://www.cubiclesoft.com/Forum/ Source to the forum software is here: http://www.cubiclesoft.com/MyProBB/ Worked fine under 5.2.0. I only depend on PHP for the forum. A straight-up phpinfo(); page seems to work fine. I upgraded by killing each webserver instance, copying the files from the ZIP file over the existing PHP directories and files, and restarting the server. So I then took the hard route of deleting the PHP directory and dumping the binaries into it from scratch and putting together a working php.ini file again...crash. So I tried to narrow down the problem and it appeared to be crashing in a VERY bizarre location: $Data = str_ireplace("\n", "<br>", $Data); So, I created a test script and eventually narrowed it down to: <? $Data = "Change tracking and management software designed to watch for abnormal system behavior.\nSuggest features, report bugs, or ask questions here."; $Data = str_ireplace("\r\n", "<br>", $Data); $Data = str_ireplace("\n", "<br>", $Data); $Data = str_ireplace("\r\n", "<br>", $Data); $Data = str_ireplace("\n", "<br>", $Data); $Data = str_ireplace("\r\n", "<br>", $Data); $Data = str_ireplace("\n", "<br>", $Data); $Data = str_ireplace("\r\n", "<br>", $Data); $Data = str_ireplace("\n", "<br>", $Data); $Data = str_ireplace("\r\n", "<br>", $Data); $Data = str_ireplace("\n", "<br>", $Data); $Data = str_ireplace("\r\n", "<br>", $Data); $Data = str_ireplace("\n", "<br>", $Data); $Data = str_ireplace("\r\n", "<br>", $Data); $Data = str_ireplace("\n", "<br>", $Data); ?> This script crashes PHP 5.2.1 everywhere. Command-line and web server (module and CGI modes). IMO, there's a bug somewhere in str_ireplace(). But it could be also more fundamental with how Zend treats variables. All that showing data around assigning a variable to itself. -- Thomas Hruska CubicleSoft President Ph: 517-803-4197 http://www.CubicleSoft.com/
