#33559 [NEW]: curl_close gives a seg fault when used on a multi cURL resource

From: dev at null dot com Operating system: Redhat 9 PHP version: 5.0.4 PHP Bug Type: Unknown/Other Function Bug description: curl_close gives a seg fault when used on a multi cURL resource Description: ------------ A common oversight if migrating from a normal cURL interface to multi-curl is leaving in a curl_close() command. This causes a PHP seg fault if performed after curl_multi_remove_handle. The problem was not reproducible all the time - one key to it being reproduced was having a. Multiple cURL handles b. Closing the first $mh using curl_multi_close; then followed by a new curl_multi_init. This may be fixed in the CVS (re #33222 - a similar but not identical problem with the function) - I am not sure. Reproduce code: --------------- $mh = curl_multi_init(); ... curl_multi_exec etc. curl_multi_remove_handle($mh,$ch); // seg fault here: curl_close($ch); Expected result: ---------------- Should give a graceful error, not a seg fault. Actual result: -------------- seg fault -- Edit bug report at http://bugs.php.net/?id=33559&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33559&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33559&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33559&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=33559&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=33559&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33559&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33559&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33559&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33559&r=support Expected behavior: http://bugs.php.net/fix.php?id=33559&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33559&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33559&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=33559&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33559&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=33559&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33559&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33559&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33559&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33559&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33559&r=mysqlcfg
