From: a at b dot c dot de Operating system: Windows XP PHP version: 5.0.3 PHP Bug Type: Reproducible crash Bug description: Invalid object callbacks not caught in array_walk()
Description: ------------ Using array_walk will crash PHP if a method of an uninstantiated object variable is used in the callback method. Other functions that take variables (at least, usort(), array_map(), array_reduce()) error out instead. There has to be at least one element in the array being walked. Reproduce code: --------------- $array = array('at least one element'); array_walk($array, array($nonesuchvar,'show')); Expected result: ---------------- PHP 4.3.10's error message for this situation reads: Warning: array_walk(): Unable to call Array() - function does not exist in ... while PHP 5.0.3 also reports a Notice-level message that $nonesuchvar is undefined. Actual result: -------------- A Notice-level message that $nonesuchvar is undefined, then a Windows core dump. -- Edit bug report at http://bugs.php.net/?id=31720&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=31720&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=31720&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=31720&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=31720&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=31720&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=31720&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=31720&r=needscript Try newer version: http://bugs.php.net/fix.php?id=31720&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=31720&r=support Expected behavior: http://bugs.php.net/fix.php?id=31720&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=31720&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=31720&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=31720&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=31720&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=31720&r=dst IIS Stability: http://bugs.php.net/fix.php?id=31720&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=31720&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=31720&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=31720&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=31720&r=mysqlcfg
