ID: 26219 User updated by: peter at normann dot com Reported By: peter at normann dot com Status: Bogus Bug Type: Regexps related Operating System: Linux kernel 2.5.74 PHP Version: 4.3.4 New Comment:
Thank you Andrei. I installed the latest pcre lib version 4.5 and linked the php-4.3.4 against it, but the problem persisted. Then I downloaded the latest snapshot of 4.3.5-dev and compiled it using the bundled libpcre 4.5 and... problem solved :-) Previous Comments: ------------------------------------------------------------------------ [2003-12-22 01:04:09] [EMAIL PROTECTED] Could not reproduce with the latest PCRE library version 4.5. ------------------------------------------------------------------------ [2003-11-12 13:00:37] [EMAIL PROTECTED] 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. I can verify the crash, however the crash is not the result of PHP code but rather due to a bug in the pcre library. Please report this bug to the maintainers of the pcre library. ------------------------------------------------------------------------ [2003-11-12 11:24:19] peter at normann dot com It's rather lengthy, but I have provided it at http://www.normann.com/bug/buggy.txt Also, the whole function can be found at http://www.normann.com/bug/bug_code.txt Thank you for taking your time... ------------------------------------------------------------------------ [2003-11-12 11:00:03] [EMAIL PROTECTED] Please provide sample of source text on which the regex operates. ------------------------------------------------------------------------ [2003-11-12 09:46:00] peter at normann dot com Description: ------------ php crashes when using the preg_match function. Code included below. Works in php4.3.3RC1 but any later version causes segmentation fault. The code is part of a text filter. $output contains text with plain text and html mixed. The idea is anything between [html] and [/html] will go untouched by the filter. I use dozens of other regular expressions, but preg_match is a sure killer. I can easily reproduce this behavior. Reproduce code: --------------- while (preg_match('/\[html]((.|\s)+?)\[\/html]/', $output, $htmlshow)) $output = str_replace($htmlshow[0], str_replace('<br />', '', strtr($htmlshow[1], array_flip(get_html_translation_table(HTML_ENTITIES)))), $output); Actual result: -------------- child pid xxxxx exit signal Segmentation fault (11) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26219&edit=1
