- bug report #2796358 (http://curl.haxx.se/bug/view.cgi?id=2796358) pointed

  out that the cookie parser would leak memory when it parses cookies that are
  received with domain, path etc set multiple times in the same header. While
  such a cookie is questionable, they occur in the wild and libcurl no longer
  leaks memory for them. I added such a header to test case 8.
