Here are my specs: Windows 2004 Professional SP4 Apache/2.0.49 My workaround is to check the PHP version, and omit the empty string parameter if version >= 5 This isn't an isolated problem, either. I became aware of this through several individuals using my open source libraries. I'm not certain what they were running but I can proably find out if you can't replicate the problem.

Restarting Apache will sometimes cause the system to revert to normal, but usually a reboot is needed. In PHP4, calling xml_parser_create("") will cause Expat to autodetect the character encoding. In the user comments of www.php.net, this is purportedly true of PHP5 as well; however this is not the case. This problem has been reproduced on a number of other machines as well. I'm not sure if the same happens with IIS. Reproduce code: --------------- $parser = xml_parser_create(""); Expected result: ---------------- a reference to the parser should be returned Actual result: -------------- Apache stalls, 100% CPU usage ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=30186&edit=1
