Test case for bug 1426

/* Trying to repeat bug report 1426

#include <stdio.h>
#include <string.h>

/* somewhat unix-specific */
#include <sys/time.h>
#include <unistd.h>

/* curl stuff */
#include <curl/curl.h>

/*
 * Simply download a HTTP file.
 */
int main(int argc, char **argv)
{
  CURL *http_handle;
  CURLM *multi_handle;

  int still_running; /* keep number of running handles */

  if(argc < 2) {
    printf("Usage: program [URL]\n");
    return 1;
  }

  curl_global_init(CURL_GLOBAL_DEFAULT);

  http_handle = curl_easy_init();

  curl_easy_setopt(http_handle, CURLOPT_URL, argv[1]);

  curl_easy_setopt(http_handle, CURLOPT_LOW_SPEED_LIMIT, 1L);
  curl_easy_setopt(http_handle, CURLOPT_LOW_SPEED_TIME, 2L);
  curl_easy_setopt(http_handle, CURLOPT_CONNECTTIMEOUT, 2L);

  /* init a multi stack */
  multi_handle = curl_multi_init();

  /* add the individual transfers */
  curl_multi_add_handle(multi_handle, http_handle);

  /* we start some action by calling perform right away */
  curl_multi_perform(multi_handle, &still_running);

  do {
    int msgs;
    CURLMsg *m;
    curl_multi_perform(multi_handle, &still_running);

    m = curl_multi_info_read(multi_handle, &msgs);

    if(m) {
      fprintf(stderr, "RETURNED %d\n", m->data.result);
      break;
    }

  } while(still_running);

  curl_multi_remove_handle(multi_handle, http_handle);

  curl_easy_cleanup(http_handle);

  curl_multi_cleanup(multi_handle);

  curl_global_cleanup();

  return 0;
}

We are setting a whole lot other options additionally: https://github.com/xbmc/xbmc/blob/master/xbmc/filesystem/CurlFile.cpp#L429

The Arch user, that reported this bug was told to gather additional logfiles with more curl debugging output which can be enabled within xbmc. I hope he will add those to the original bugreport so that it gets easier to find the issue.

Thanks very much to find that regression.
