[Message part 1 (text/plain, inline)]

Trying to `edebug-defun' on `widget-default-create' produces an error.

This is reproducible in today's master (see below for config) as well as
28.2 tag (same config options).

Reproducer:

    ;; -nw or not makes no difference
    $ src/emacs -Q -nw -l lisp/wid-edit.el{,}

    ;; line 1640
    C-s defun widget-default-create RET
    C-u C-M-x

Full backtrace as shown on the error is attached.

Thanks, should be fixed now on the emacs-29 branch.

Stefan, is that the right fix?  I'm asking because the ELisp manual is
not entirely clear on this, and I see at least one more case of

   (declare (debug body))

in our tree, in benchmark.el.  Is that also a bug?

Sorry, fell through.

I'd have used

   (declare (debug t))

but the

   (declare (debug (body)))

does the trick as well, yes.
