Snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. Thank you for the report, and for helping us make PHP better. The bug is already fixed in PHP-5.3 with Garbage Collector which collects cyclic references. In PHP-5.2 this bug will never fixed. You can get the same memory leaks with smaller script: <?php $array = array(1,2,3); $array["foo"] = &$array; $array["blah"] = &$array; ?> In case your script creates cyclic structures, in 5.2 it's better to break cycles before exit manually. <?php $array = array(1,2,3); $array["foo"] = &$array; $array["blah"] = &$array; $array["foo"] = null; $array["blah"] = null; ?> Previous Comments: ------------------------------------------------------------------------ [2008-12-28 08:37:47] rutekp at freelance-worker dot net Description: ------------ When I try to excedue code which is below without: $array["foo"] = null; $array["blah"] = null; have errors like Actual location (location was relayed) Freeing 0x05298E00 Reproduce code: --------------- --TEST-- Test session_encode() function : variation --SKIPIF-- <?php include('skipif.inc'); ?> --FILE-- <?php ob_start(); echo "*** Testing session_encode() : variation ***\n"; var_dump(session_start()); $array = array(1,2,3); $array["foo"] = &$array; $array["blah"] = &$array; $_SESSION["data"] = &$array; var_dump(session_encode()); var_dump(session_destroy()); echo "Done"; ob_end_flush(); ?> --EXPECTF-- *** Testing session_encode() : variation *** bool(true) string(64) "data|a:5:{i:0;i:1;i:1;i:2;i:2;i:3;s:3:"foo";R:1;s:4:"blah";R:1;}" bool(true) Done Actual result: -------------- [Thu Oct 30 20:56:43 2008] Script: 'ext/session/tests/session_encode_variation5.phpt' /root/src/php-5.2.6/Zend/zend_vm_execute.h(3565) : Freeing 0x05293DD8 (24 bytes), script=ext/session/tests/session_encode_variation5.phpt Last leak repeated 2 times [Thu Oct 30 20:56:43 2008] Script: 'ext/session/tests/session_encode_variation5.phpt' /root/src/php-5.2.6/Zend/zend_vm_execute.h(3610) : Freeing 0x05298CC8 (72 bytes), script=ext/session/tests/session_encode_variation5.phpt /root/src/php-5.2.6/Zend/zend_API.c(827) : Actual location (location was relayed) Last leak repeated 1 time [Thu Oct 30 20:56:43 2008] Script: 'ext/session/tests/session_encode_variation5.phpt' /root/src/php-5.2.6/Zend/zend_vm_execute.h(3596) : Freeing 0x05298E00 (71 bytes), script=ext/session/tests/session_encode_variation5.phpt /root/src/php-5.2.6/Zend/zend_hash.c(388) : Actual location (location was relayed) Last leak repeated 2 times [Thu Oct 30 20:56:43 2008] Script: 'ext/session/tests/session_encode_variation5.phpt' /root/src/php-5.2.6/Zend/zend_execute.c(834) : Freeing 0x05299050 (24 bytes), script=ext/session/tests/session_encode_variation5.phpt [Thu Oct 30 20:56:43 2008] Script: 'ext/session/tests/session_encode_variation5.phpt' /root/src/php-5.2.6/Zend/zend_hash.c(247) : Freeing 0x052990C0 (75 bytes), script=ext/session/tests/session_encode_variation5.phpt Last leak repeated 1 time === Total 11 memory leaks detected === ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46960&edit=1
