whether forget to free memory?

[fanlb]

there's some code like following in file url.c :

/* Check whether two URL-s are equivalent, i.e. pointing to the same
   location.  Uses parseurl to parse them, and compares the canonical
   forms.

   Returns 1 if the URL1 is equivalent to URL2, 0 otherwise.  Also
   return 0 on error.  */
int
url_equal (const char *url1, const char *url2)
{
  struct urlinfo *u1, *u2;
  uerr_t err;
  int res;

  u1 = newurl ();
  err = parseurl (url1, u1, 0);
  if (err != URLOK)
    {
      freeurl (u1, 1);
      return 0;
    }
  u2 = newurl ();
  err = parseurl (url2, u2, 0);
  if (err != URLOK)
    {
      freeurl (u2, 1);
      return 0;
    }
  res = !strcmp (u1->url, u2->url);
  freeurl (u1, 1);
  freeurl (u2, 1);
  return res;
}

Would u1 been leaved in memory,if allocation for u1 were succeeded but u2 failed?
