#25932 [Opn->Bgs]: s (PCRE_DOTALL) modifier makes Apache2 crash

ID: 25932 Updated by: iliaa@php.net Reported By: dcahh at gmx dot de -Status: Open +Status: Bogus Bug Type: PCRE related Operating System: W2K Prof PHP Version: 4.3.4RC2 New Comment: Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. This code does infact cause a crash (not limited to Win32). However, the crash is the result of a bug in the PCRE library, please report it to the authors of said library. This is not a PHP bug.
