I'm not sure what you are trying to achieve by using the infinite loop. There's a more direct way.

    void free_circularly_linked_list(struct node *head)
    {
      struct node *a = head->next;
      while (a != head) {
        struct node *b = a->next;
        free(a);
        a = b;
      }
      free(head);
    }

Great example, by the way!
