emacs 27.2: edebug prints 'Stop' instead of evaluating expression at point

[Ralf Fassel]

Just upgraded from Opensuse 15.3 (emacs 25.3) to Opensuse 15.4, in the
process emacs was upgraded to 27.2.

In emacs 27.2 when I step through functions via edebug, it only prints a
non-informative 'Stop' in the minibuffer, where emacs-25 printed the
value of the current expression.

I have not the slightest idea where to start to look for what might
cause this or how it might be changed back to the previous behaviour.
Any pointers?

Your Emacs distribution should include the Emacs Lisp Reference manual
(elisp), which contains a chapter titled "Debugging Lisp Programs". You
should be able to read that by having Info go to '(elisp) Debugging'.
It might be able to provide you with the information you need.

Also, see the NEWS file (<C-h n>) for Emacs 27 for any description of
changes to debugging. (And, <C-u 26 C-h n> for possible changes that
were made in Emacs 26.)
