From: dimox at inbox dot lv Operating system: Windows XP Pro SP2 PHP version: 4.4.2 PHP Bug Type: Reproducible crash Bug description: Regxp couses PHP script crach on Windows Description: ------------ Regxp couses PHP script crach on Windows. On Linux Server it works fine, but I use Windows server on my PC for development. I try this code on my own PC with Apache/1.3.34 (Win32) PHP/4.4.2 and on another PC with Apache/1.3.34 (Win32) PHP/4.4.1. On my PC this code souses Apache crash, but on another PC this code couses only script crash. I looking information about this bug anywere, but can't find anything useful, except http://bugs.php.net/bug.php?id=27735. I try with logs disconnection, but it doesn't change anything. Help ... Reproduce code: --------------- $regex = '/block\s*name=\"([^\"]+)\"\s*\%\>((.(?!(block\s)))+?)\blockend/is'; while(preg_match_all($regex, $text, $block_matches, PREG_SET_ORDER)){ ... } Expected result: ---------------- $block_matches array with results of regular expression matches. I need in this to parse blocks like block name="name1" something block name="name2" something else ... blockend blockend Actual result: -------------- "Server not found" or "The page cannot be displayed" in browser. After simplification of code to: $regex = '/block\s*name=\"([^\"]+)\"\s*\%\>(.+?)\blockend/is'; while(preg_match_all($regex, $text, $block_matches, PREG_SET_ORDER)){ ... } all works fine(remooved lookahead assertion). If i add () around the '.' - script crash again. $regex = '/block\s*name=\"([^\"]+)\"\s*\%\>((.)+?)\blockend/is'; -- Edit bug report at http://bugs.php.net/?id=37239&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37239&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=37239&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37239&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37239&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37239&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37239&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37239&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37239&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37239&r=support Expected behavior: http://bugs.php.net/fix.php?id=37239&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37239&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37239&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37239&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37239&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37239&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37239&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37239&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37239&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37239&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37239&r=mysqlcfg
