PHP Bug Type: cURL related
Bug description: cURL Special case Segfault
I've found, by complete accident a very strange curl segfault produced by
the following code:
$ch = curl_init ("ftp://localhost/itworked.txt";);
curl_setopt($ch, CURLOPT_USERPWD, "php:foobar");
$fr = fopen("curl_ex6.php");
curl_setopt($ch, CURLOPT_INFILE, $fr);
curl_setopt($ch, CURLOPT_UPLOAD, true);
curl_exec($ch);
fclose($fr);
curl_close($ch);
Two important parts to this segfault:
1) fopen() cannot actually be correctly formatted. It must fail to
specify the mode.
2) The username, password set by curl_setopt must actually be a real
username/password that works. If you provide a fake password, everything
is fine.. but if you actually used a real password you segfault.
here's the BT:
