title change Previous Comments: ------------------------------------------------------------------------ [2005-09-08 06:54:01] blucasco at gmail dot com Also, I have tried with both curl 7.13.x and 7.14.1 compiled in (separate builds) with the same type of seg-fault after several iterations. ------------------------------------------------------------------------ [2005-09-08 06:47:23] blucasco at gmail dot com Description: ------------ This code causes seg fault on any version of PHP 5, including newest CVS build (php5-200509080230). Are there threading issues? Is curl_multi not reliable? I seem unable to test with --enable-thread-safety or --enable-experimental-zts (doesn't compile in properly) so I can't confirm. Reproduce code: --------------- <?php $connomains = array( "http://www.cnn.com/";, "http://www.canada.com/";, "http://www.yahoo.com/"; ); while(1) { $mh = curl_multi_init(); foreach ($connomains as $i => $url) { $conn[$i] = curl_init($url); curl_setopt($conn[$i], CURLOPT_RETURNTRANSFER, 1); curl_multi_add_handle ($mh,$conn[$i]); } // start performing the request do { $mrc = curl_multi_exec($mh, $active); } while ($mrc == CURLM_CALL_MULTI_PERFORM); while ($active and $mrc == CURLM_OK) { // wait for network if (curl_multi_select($mh) != -1) { // pull in any new data, or at least handle timeouts do { $mrc = curl_multi_exec($mh, $active); } while ($mrc == CURLM_CALL_MULTI_PERFORM); } } if ($mrc != CURLM_OK) { print "Curl multi read error $mrc\n"; } // retrieve data foreach ($connomains as $i => $url) { if (($err = curl_error($conn[$i])) == '') { $res[$i]=curl_multi_getcontent($conn[$i]); } else { print "Curl error on handle $i: $err\n"; } curl_multi_remove_handle($mh,$conn[$i]); curl_close($conn[$i]); } curl_multi_close($mh); print_r($res); } ?> Expected result: ---------------- Expected: continous loop after everything is properly closed. Actual result: -------------- Segmentation fault ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34420&edit=1
