Thanks guys for the help. I tried linking statically as described
below and it did produce a static library; however, it is still
crashing. It is crashing here in asyn-thread.c when it is trying to
free the hostname.

 /*
 * destroy_async_data() cleans up async resolver data and thread handle.
 */
static void destroy_async_data (struct Curl_async *async)
{
  if(async->hostname)
    free(async->hostname); <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

  if(async->os_specific) {
    struct thread_data *td = (struct thread_data*) async->os_specific;

    if(td->thread_hnd != curl_thread_t_null)
      Curl_thread_join(&td->thread_hnd);

    destroy_thread_sync_data(&td->tsd);

    free(async->os_specific);
  }
  async->hostname = NULL;
  async->os_specific = NULL;
}

Here is how I set the hostname (URL) in my code

curlStatus = curl_easy_setopt(m_hCurl, CURLOPT_URL, szURL)

where szURL is a local char* variable.

any help would be greatly appreciated :) I've been stuck on this thing
for 2 weeks now.

Thanks,
J
