Test script: --------------- <?php $transfers = 1; $callback = function($parent, $passed) use (&$transfers) { curl_setopt($passed, CURLOPT_WRITEFUNCTION, function ($ch, $data) { echo "Received ".strlen($data)."\n"; return strlen($data); }); $transfers++; return CURL_PUSH_OK; }; $mh = curl_multi_init(); curl_multi_setopt($mh, CURLMOPT_PIPELINING, CURLPIPE_MULTIPLEX); curl_multi_setopt($mh, CURLMOPT_PUSHFUNCTION, $callback); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'https://http2.golang.org/serverpush'); curl_setopt($ch, CURLOPT_HTTP_VERSION, 3); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // FIXME, this line crashes everything. Without it, everything is fine. curl_setopt($ch, CURLOPT_TIMEOUT, 30); curl_multi_add_handle($mh, $ch); $active = null; do { $status = curl_multi_exec($mh, $active); do { $info = curl_multi_info_read($mh); if (false !== $info && $info['msg'] == CURLMSG_DONE) { $handle = $info['handle']; if ($handle !== null) { $transfers--; curl_multi_remove_handle($mh, $handle); curl_close($handle); } } } while ($info); } while ($transfers); curl_multi_close($mh); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77497&edit=1
