#49711 [NEW]: Memory Leak in Deprecated Methods

From: kristina at 10gen dot com Operating system: Windows PHP version: 5.3.0 PHP Bug Type: Unknown/Other Function Bug description: Memory Leak in Deprecated Methods Description: ------------ A method with the ZEND_ACC_DEPRECATED flag will cause memory usage to increase each time it's called through PHPUnit. (It doesn't occur with a PHP program run with "php script.php", so it might have something to do with reflection.) It occurs in 5.2.* and 5.3.*, only on Windows. I've written a small PHP extension that demonstrates this bug. It is available at http://github.com/beaddy1238/PHP-Memleak. Reproduce code: --------------- Compile the extension by putting the config.w32, php_mongo.h, and mongo.c files in a pecl\mongo dir. From the pecl\mongo directory, run: phpunit tests\MongoRunner.php It print out the memory used at the beginning and end of the function. The function calls Mongo->lastError() (an empty method) 10000 times. Expected result: ---------------- I expect the memory usage to stay the same. Actual result: -------------- The more times Mongo->lastError is called, the more memory is used. This stops happening if ZEND_ACC_DEPRECATED is removed from mongo.c. -- Edit bug report at http://bugs.php.net/?id=49711&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=49711&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=49711&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=49711&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=49711&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=49711&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=49711&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=49711&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=49711&r=needscript Try newer version: http://bugs.php.net/fix.php?id=49711&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=49711&r=support Expected behavior: http://bugs.php.net/fix.php?id=49711&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=49711&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=49711&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=49711&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=49711&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=49711&r=dst IIS Stability: http://bugs.php.net/fix.php?id=49711&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=49711&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=49711&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=49711&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=49711&r=mysqlcfg
