(memory_get_usage(true) - $start_mem) . "]\n<br>"; // this does not leak $start_mem = memory_get_usage(true); for ($i = 0; $i < $max; $i++) { leak(array($i)); } echo 'leak mem2: [' . (memory_get_usage(true) - $start_mem) . ']'; function leak($leak = array()) {} ?> Expected result: ---------------- leak mem1: [0] leak mem2: [0] Actual result: -------------- leak mem1: [87818240] leak mem2: [0] -- Edit bug report at http://bugs.php.net/?id=45047&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=45047&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=45047&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=45047&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=45047&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=45047&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=45047&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=45047&r=needscript Try newer version: http://bugs.php.net/fix.php?id=45047&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=45047&r=support Expected behavior: http://bugs.php.net/fix.php?id=45047&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=45047&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=45047&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=45047&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=45047&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=45047&r=dst IIS Stability: http://bugs.php.net/fix.php?id=45047&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=45047&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=45047&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=45047&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=45047&r=mysqlcfg
