In GNU Emacs 29.0.50 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.20, cairo version 1.16.0)
 of 2022-02-02 built on orion
Repository revision: ed13b0d0f427df333f8e1f9a24015c354da4c62f
Repository branch: rgr-ietf-drums-date
Windowing system distributor 'The X.Org Foundation', version 11.0.12003000
System Description: openSUSE Leap 15.3

   While developing tests for ietf-drums.el, I found that if
ietf-drums-parse-address is asked to do RFC2047 decoding, it does not by
itself load or declare the necessary rfc2047.el code.  So evaluating

        (require 'ietf-drums)
        (ietf-drums-parse-address
          "=?utf-8?B?0JfQtNGA0LDMgdCy0YHRgtCy0YPQudGC0LUh?= <foo@goo.ru>"
          t)

gets a "(void-function rfc2047-decode-string)" error.  The patch below
includes a possible fix plus a new test file (with the code above as a
regression test).

Subject: [PATCH] Add ietf-drums tests, fix parse-address decoding

* test/lisp/mail/ietf-drums-tests.el (ietf-drums-tests):  Test most of
     lisp/mail/ietf-drums.el functionality.
* lisp/mail/ietf-drums.el:
   + (ietf-drums-parse-address):  Bug fix:  Require rfc2047 when needed.
