Good News: I have a FreeBSD 12.1 VM hanging around. Installing Emacs 28
on that machine, trying your recipe with my remote Ubuntu machine, and
voilà - it hangs. Great :-)

Well, C-g several times doesn't kill the compile process, but so what: I
can test now. Will play with this next days, as time permits.

Ah, I didn't know. Good to have it as fallback, I don't care to share
some few $s ...  But I haven't used this type of OS ever, so I would
need to learn how to install Emacs there.

It is Tramp 2.5.0, which I have released meanwhile via GNU ELPA. So you
might try to install it from there. Emacs 28, which will carry it
built-in, is still months away from a release. I wouldn't even bet that
this will happen this year; currently Emacs 27.2 has started its
pretest. However, I plan regular Tramp 2.5 releases via GNU ELPA (once a
month or so).

What do you mean with "crash-and-exit emacs"? Is it just because of the
changed Tramp version?

There have been bug reports that Tramp could crash Emacs on macOS. But
finally, it wasn't a Tramp issue, but rather a bug in Emacs which was
uncovered by Tramp. This is fixed now in the Emacs repository, see
bug#24472, bug#37299, bug#37557. The bugs are merged, so it seems to be
the same problem.

If you see other problems related to Tramp 2.5.0, pls report. I'll
happily try to fix them.
