ID: 35968 Updated by: derick@php.net Reported By: levi at alliancesoftware dot com dot au -Status: Open +Status: Closed Bug Type: Scripting Engine problem PHP Version: 5CVS-2006-01-11 (CVS) New Comment: Thank you for your bug report. This issue has already been fixed in the latest released version of PHP, which you can download at http://www.php.net/downloads.php The upgrade path from PHP 5.0 is PHP 5.1.1. So simply use PHP 5.1.1... Besides that, this is not a critical problem as PHP will clean it up at the end of the request.

If it was a deliberatel fix in 5.1, can the fix be backported to the 5.0 tree too? Reproduce code: --------------- #!/usr/local/src/php5/php-5.0CVS/php-src/sapi/cli/php <? try { $x = 0; switch ($x) { default: throw new Exception('bad thing happened'); } } catch (Exception $z) { } ?> Expected result: ---------------- Nothing Actual result: -------------- With --enable-debug: /usr/local/src/php5/php-5.0CVS/php-src/Zend/zend_execute.c(675) : Freeing 0x09A4C354 (16 byt es), script=./tX.php5 === Total 1 memory leaks detected === ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=35968&edit=1
