I use the packages from Archlinux repository (php, libcurl 7.27.0 x86_64). I get the same results with a current ubuntu distribution. Test script: --------------- <?php $curl = curl_init(); $fd = fopen('/tmp/test', 'wb'); curl_setopt($curl, CURLOPT_FILE, $fd); $copy = curl_copy_handle($curl); var_dump($copy); curl_close($copy); curl_close($curl); fclose($fd); Expected result: ---------------- no segfault Actual result: -------------- segfault: #0 0x00007ffff5ca6f46 in ??
