#37171 [NEW]: crashes when using curl_multi_*

From: bishopx at quick dot cz Operating system: win32 PHP version: 5.1.2 PHP Bug Type: cURL related Bug description: crashes when using curl_multi_* Description: ------------ php_curl.dll is the cause of frequent crashes when using curl_multi_*() functions, especially curl*_close() and curl_multi_remove_handle(). However, even other functions sometimes cause a crash (I removed the above ones). The situation in the latest snapshots remains the same. It looks like a poor thread synchronisation. Apache 2.2.x used. Reproduce code: --------------- This should work fine: http://php.net/manual/en/function.curl-multi-exec.php#48813 ..but you may have to increase the number of links in $connomains, or change them to pictures. Expected result: ---------------- The code doesn't crash the webserver. Actual result: -------------- The code often crashes the webserver (not always). -- Edit bug report at http://bugs.php.net/?id=37171&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37171&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=37171&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37171&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37171&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37171&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37171&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37171&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37171&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37171&r=support Expected behavior: http://bugs.php.net/fix.php?id=37171&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37171&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37171&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37171&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37171&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37171&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37171&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37171&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37171&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37171&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37171&r=mysqlcfg
