Isn't this a bug in `idna.el' then?  Cc-ing Simon therefore.

Does it mean, that you can reproduce the problem when evaluating this
expression after starting "emacs -Q"?

Thank you for the comment.

After "make maintainer-clean" in emacs/lisp directory, I successfully
bootstrapped the latest emacs. And then I'm trying this problem again.

No.

After starting "emacs -Q", loaded /some/where/idna.el, opened
gnus/lisp/message.el (no load of gnus) and evaluated this expression. It
was successfull.

(idna-to-ascii "räksmörgås")
"xn--rksmrgs-5wao1o"

Thanks.

This doesn't seem to be reproducible by anyone, so I'm closing the
report.

It doesn't work that way. Either send a mail to 92-done (as I did in
this mail), explaining in the body why the bug is closed; or send

close 92
stop

at the start of the body in a message to control@debbugs.
