From: peter at normann dot com Operating system: Linux kernel 2.5.74 PHP version: 4.3.4 PHP Bug Type: Regexps related Bug description: Segmentation fault using regexp in php versions later than 4.3.3RC1
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 bug report at http://bugs.php.net/?id=26219&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=26219&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=26219&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=26219&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=26219&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=26219&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=26219&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=26219&r=support Expected behavior: http://bugs.php.net/fix.php?id=26219&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=26219&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=26219&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=26219&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=26219&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=26219&r=dst IIS Stability: http://bugs.php.net/fix.php?id=26219&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=26219&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=26219&r=float
