From: ask at eternal-newbie dot dk Operating system: linux PHP version: 4.3.4 PHP Bug Type: PCRE related Bug description: calling preg_match at _very_ specific points, will cause apache to crash
Description: ------------ in my functions.php (http://wiki.dgsnet.dk/functions.phps) i got a class called user with a function called in_group(). This function calls a global function called isint();, this function uses preg_match. If the in_group() function is called from withith the global makeoutput function or from a function called from without the makeoutput function. the the call in in_group() to isint() will cause the apache child to crash. i cannot get a gdb file, since it's the child and not the parant server which is crashing. However the log states clearly that it returns a segmentation fault. I might need to note that in_group is being called several times before makeoutput() is started and that works fine. Reproduce code: --------------- http://wiki.dgsnet.dk/functions.phps Expected result: ---------------- that apache/php didn't crash. Actual result: -------------- see description. -- Edit bug report at http://bugs.php.net/?id=27033&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=27033&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=27033&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=27033&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=27033&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=27033&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=27033&r=needscript Try newer version: http://bugs.php.net/fix.php?id=27033&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=27033&r=support Expected behavior: http://bugs.php.net/fix.php?id=27033&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=27033&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=27033&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=27033&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=27033&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=27033&r=dst IIS Stability: http://bugs.php.net/fix.php?id=27033&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=27033&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=27033&r=float
