To all,

I had a memory leak when using CURLOPT_USERPWD and making multiple requests
with curl_easy_perform().

I tracked the memory leak to this area of code:

http.c:

CURLcode Curl_http_connect(struct connectdata *conn)
{
....
   data->state.auth_host = strdup(conn->hostname);
....

It seems to me that when you make multiple requests, the strdup on repeated
requests leaks memory. Curl_close() which is called from
curl_easy_cleanup() does free this memory; however, I am making multiple
calls to curl_easy_perform() before I call curl_easy_cleanup().

I added the following lines of code:

    if (data->state.auth_host) {
       /* Free to avoid leaking memory on multiple requests*/
       free(data->state.auth_host);
    }
   data->state.auth_host = strdup(conn->hostname);

which cleaned up my leak.

Does this change make sense?
