From: ronald dot muller at gmail dot com Operating system: apache PHP version: 5.2.9 PHP Bug Type: GD related Bug description: imagecreatefromjpeg() crashes i.s.o. return FALSE
Description: ------------ imagecreatefromjpeg() should return FALSE on errors (as documented), not crash - hence aborting the php script. http://www.plasticdaisy.net/dlvs/dlvs.php?c=pr shows "Fatal error: Allowed memory size of 33554432 bytes exhausted" and aborts the script. The crash occurs because memory_limit is exceeded, as mentioned in previous submissions on the same bug. In the example case a 3.8MB jpg is expanded internally to somewhere in between 32MB and 64MB. Increasing the memory_limit does not solve the bug, it merely hides it again. The function should be made according to spec, i.e. return FALSE. Then the php script can act properly on this error. Reproduce code: --------------- ini_set('memory_limit', $TOO_SMALL); $someVar = imagecreatefromjpeg($img); echo $someVar; Expected result: ---------------- return FALSE i.s.o. crash, as documented. Actual result: -------------- Fatal error: Allowed memory size of 33554432 bytes exhausted http://www.plasticdaisy.net/dlvs/dlvs.php?c=pr -- Edit bug report at http://bugs.php.net/?id=48179&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48179&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48179&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48179&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48179&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48179&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48179&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48179&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48179&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48179&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48179&r=support Expected behavior: http://bugs.php.net/fix.php?id=48179&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48179&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48179&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48179&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48179&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48179&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48179&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48179&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48179&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48179&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48179&r=mysqlcfg
