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

whenever I use undefined varaible this message is triggered:

(message "%s" some-undefined-variable)

message: Symbol's value as variable is void: unread-command-char

(in *Messages* buffer)

or

(mapcar 'car some-undefined-var)

mapcar: Symbol's value as variable is void: unread-command-char

when it's in .emacs file or when I call eval-last-sexp (C-x C-e)

Strange but when I call emacs -q I don't have that error I have
message from debuger (*Backtrace* buffer)

Emacs version:

GNU Emacs 24.3.1 (x86_64-pc-linux-gnu, GTK+ Version 3.8.2) of 2013-07-27 on
roseapple, modified by Debian

I don't know what inside by .emacs is causing this, I don't have
unread-command-char in any mode I'm using.

Any idea how to find the root of the bug?

When I run emacs -q and run M-x load-file "~/.emacs" I don't get that message
and have normal message with backtrace.

So this must be somewhere in Emacs not in my customizations.

I'm not sure what this bug report is exactly about.  That the debugger
doesn't pop up in your situation?  Note that this is controlled by the
user option `debug-on-error'.

Or is it about the error you get about `unread-command-char' when
loading your Emacs?  Then you should bisect your config file and try to
find out what causes the error, i.e., please post a recipe starting from
emacs -Q reproducing the problem.  Also a backtrace of the error you get
would be helpful.

Michael.

It pup up message with `unread-command-char` `debug-on-error' have no effect,
it don't enter debuger. And it have nothing to do with my config since when I
load .emacs file using load-file it work fine, I enter debuger. Also I run
emacs with --debug-init.

So it's wrong message and debuger don't work.

The *Messages* have:

Entering debugger...
message: Symbol's value as variable is void: unread-command-char

also *Backtrace* buffer is empty and it's not show up. I have the same when I
try to execute non-exiting function:

(foobar)

foobar: Symbol's value as variable is void: unread-command-char

It's Emacs fault since my .emacs run fine when I run it using load-file.

PS: are there other files that Emacs can run on init, maybe I miss something?

Ok, I found the reason, I had "emacs-24.1/lisp/emacs-lisp" in my load-path
path.
