ID: 46551 Comment by: donquixote dot phplist at googlemail dot com Reported By: johnpupu at gmail dot com Status: No Feedback Bug Type: PCRE related Operating System: FreeBSD 7.0-RELEASE-p4 PHP Version: 5.2.6 New Comment: Sorry for the multipost. When I tried this with Opera I always got this error message: "Authentication failed: Incorrect username Authentication failed: Incorrect username Warning: Cannot modify header information - headers already sent by (output started at /home/Web/sites/php-bugs-web/include/auth.inc:30) in /home/Web/sites/php-bugs-web/report.php on line 201" Previous Comments: ------------------------------------------------------------------------ [2009-09-28 05:27:33] donquixote dot phplist at googlemail dot com I found a regex / text combination that causes my apache to crash / restart with preg_replace. The example is a reduced version of Drupal's CSS compression regex. The regex is not overly complex, and the text is not overly long. Reproducing this depends on system configuration: On my webspace it does not crash. But, on my localhost it makes a reproducible crash. Removing a few letters in the regexped text (no matter which) makes the bug not happen.
