#49345 [NEW]: To much used memory

From: pearl1985 at interia dot pl Operating system: Windows XP x64 PHP version: 5.3.0 PHP Bug Type: Performance problem Bug description: To much used memory Description: ------------ When I was using function lambda in class, I saw that it is using a lot of operating memory. I saw this error when the script was sending e-mails reports to users registered in my service. Reproduce code: --------------- <?php class example { function test() { $var = create_function('', '$a = 1;$b=2;$c=$a+$b;'); $var(); unset($var); } } $example = new example; for($i=0;$i<=10000;$i++) { $example->test(); } echo 'Results after remove lambda'."\n"; echo 'Memory limit: '.ini_get('memory_limit')."\n"; echo 'Usage: '. round(memory_get_usage()/1024/1024, 1)."\n"; echo 'Peak:'. round(memory_get_peak_usage()/1024/1024, 1); echo "\n"; ?> Expected result: ---------------- I expected a slight growth of operating memory usage by script. By using endless loop, I expect the script will be executing even for 2 hours, thanks to correction of appropriate php configuration directive. Actual result: -------------- When I used endless loop while(true), php engine ended its work after 2 minutes,generating error "PHP Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate 40961 bytes)" -- Edit bug report at http://bugs.php.net/?id=49345&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=49345&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=49345&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=49345&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=49345&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=49345&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=49345&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=49345&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=49345&r=needscript Try newer version: http://bugs.php.net/fix.php?id=49345&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=49345&r=support Expected behavior: http://bugs.php.net/fix.php?id=49345&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=49345&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=49345&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=49345&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=49345&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=49345&r=dst IIS Stability: http://bugs.php.net/fix.php?id=49345&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=49345&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=49345&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=49345&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=49345&r=mysqlcfg
