bug#10577: Subject: 23.4; edebug-defun fails with `completion-table-dynamic'

[Andreas Röhler]

Hi,

with Emacs -Q,

doing M-x edebug-defun

over `completion-table-dynamic' from minibuffer.el results in

edebug-syntax-error: Invalid read syntax: "Expected lambda expression"

;;;;;;;;;

Thanks all,
Andreas

I can't reproduce this on the trunk.  Can you reproduce it with the
Emacs-24 pretest?

Try edebugging emacs 23's completion-table-dynamic in the trunk.
You need to explicitly load cl first to get it to work.
I've often wondered if edebug can figure this out for itself somehow
(perhaps look for eval-when-compile's in the defining file?).
