#41871 [NEW]: mysql_free_result does not free result for a referenced result variable

From: kulakov74 at yandex dot ru Operating system: Linux / Windows PHP version: 5.2.3 PHP Bug Type: MySQL related Bug description: mysql_free_result does not free result for a referenced result variable Description: ------------ When I call mysql_free_result($Res) I expect I won't be able to use the result in calls to mysql_fetch_array() etc. But if $Res is passed by reference as a function parameter and is copied to another variable the result is not freed and I can still use it. I realize this is a VERY unlikely condition and I found it by accident (mixed 2 lines of code and got surprised to see no error). Also this might well be intentional behavior. Anyway, just in case. Reproduce code: --------------- a($Res); function a(&$Res){ $Res=mysql_query("Show Tables"); $Res1=$Res; mysql_free_result($Res); mysql_fetch_array($Res); //still works! } Expected result: ---------------- Warning: mysql_fetch_array(): 7 is not a valid MySQL result resource in Actual result: -------------- No errors -- Edit bug report at http://bugs.php.net/?id=41871&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41871&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41871&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41871&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41871&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41871&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41871&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41871&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41871&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41871&r=support Expected behavior: http://bugs.php.net/fix.php?id=41871&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41871&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41871&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41871&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41871&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41871&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41871&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41871&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41871&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41871&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41871&r=mysqlcfg
