Subject: Subject: 23.4; edebug-defun fails with `completion-table-dynamic'
Date: Sun, 22 Jan 2012 14:51:05 +0100

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?).

I'm unable to reproduce this in Emacs 27, so I'm going to go ahead and
guess that it's been fixed in the eight years since it was reported, and
I'm closing this bug report.  If you're still seeing this, please reopen.
