#47038 [NEW]: Memory leak in include()

From: tim at digicol dot de Operating system: Linux (Debian 4.0 x86) PHP version: 5.3CVS-2009-01-08 (snap) PHP Bug Type: Scripting Engine problem Bug description: Memory leak in include() Description: ------------ With today's PHP 5.3 snapshot, include() on my Linux box leaks memory; I've noticed this because we're using long-running scripts with the PHP CLI (where Smarty's fetch/display methods call include()...). This doesn't happen with PHP 5.2.6. I tested with an unchanged copy of php.ini-recommended and just './configure' without any options, on Debian Linux 4.0, running in VMware Fusion on my Intel Mac. Thanks for looking into this, and for the great work on PHP! Reproduce code: --------------- <?php // Create an empty file touch('empty.txt'); while (true) { include('empty.txt'); echo memory_get_usage() . "\n"; } ?> Expected result: ---------------- No increase in memory usage. Actual result: -------------- Memory usage increases constantly, until PHP exits because the memory limit is exceeded. -- Edit bug report at http://bugs.php.net/?id=47038&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47038&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47038&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47038&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47038&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47038&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47038&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47038&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47038&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47038&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47038&r=support Expected behavior: http://bugs.php.net/fix.php?id=47038&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47038&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47038&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47038&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47038&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47038&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47038&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47038&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47038&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47038&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47038&r=mysqlcfg
