I've a similar error using this piece of PHP code

<?php

$url = "http://willneverexist42";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);

curl_exec($ch);
var_dump(curl_error($ch));
var_dump(curl_errno($ch));
curl_close($ch);
?>

Expected is something like

string(55) "Could not resolve host: (willneverexist42); Host not found"

Currently the error message

string(45) "Could not resolve host: (nil); Host not found"

This happens when php is compiled with 7.29.0 and master as well, but pass on 7.27.0 (and below i suppose). Windows only.

** [bugs:#1191] When using a wrong hostname in --interface, the wrong host name appears in the error message**

While testing my patch for #1189 I discovered a related problem which is pre-existing: I can reproduce it on the current git master. For test 1084, even though the exit code is correct (45, CURLE_INTERFACE_FAILED) the error text is wrong and confusing:
src/curl --interface DoesNotExist.example.com http://www.google.com/
curl: (45) Could not resolve host: www.google.com (Domain name not found)
Actually it failed to resolve DoesNotExist.example.com, not www.google.com like the error message says. If you use --proxy then the error message says "Could not resolve proxy" which is also not true.
I am not sure what the best way to fix this would be (I can think of a hack or two), but I just wanted to document it single I noticed it.
