Getting error when passing negative arguments to a function

[kaushalmodi]

When I tried doing M- -1 M-f, I got the below error in the mode-line.

Should that be reported as emacs bug or is it a bug in this package?

Error running timer `guide-key/polling-function': (wrong-type-argument sequencep #<EMACS BUG: INVALID DATATYPE (PVEC 0xfffffffffffffffe) Save your buffers immediately and please report this bug>)

I also meets this error.

Please tell me the version of your Emacs and guide-key.
How often does this error happen? How about other commands with universal-negative-argument?

Hi,

I am using the stable 24.4 version of GNU emacs and Version: 20141207.907 of guide-key (latest from Melpa as of now).

This error happens every time I hit ESC - 1, even before I continue entering a binding like M-f. C-u M-f works fine (no error).

The issue is repeatable when using any negative prefix: ESC - 2, ESC - 3

[kai2nenobu]

Hmm, I sometimes get this error but not always. I'll survey conditions to reproduce the error and report to Emacs developers.

BTW, does this error prevent a command behavior? For example, when you type ESC - 1 M-f, does the cursor move backward one word? Or doesn't the cursor move?

If this error prevents that command behavior, I'll revert this feature.

[kaushalmodi]

No, the command behavior is not altered, it works as expected.
Just that I see that error in the minibuffer.

Thanks.

I'm seeing this error too, but only on Emacs 24.4.1 on Windows (7, 64 bit). I don't see the error on GNU/Linux or Mac OS X.

If I enter ESC - 1, see the error, and then enter ESC - 1 again it reliably crashes Emacs.

[kai2nenobu]

@johnmastro Thanks for your informatin. But in my envirinment, both in Windows and in Linux this error happens.

@kaushalmodi @johnmastro Are you using key-chord with guide-key? If you so, turn off key-chord-mode and try again.
In my case, key-chord-inut-method seems to conflict with guide-key.

[kaushalmodi]

You're correct! That error does not show up after disabling key-chord-mode.

[johnmastro]

Yep, confirmed for me too: no problem without key-chord-mode.

[kaushalmodi]

Funny enough, this error occurs only when using -1, -2 or -3 negative prefixes. -4 does not cause a problem.

[kai2nenobu]

It depends on your key-chord bindings.
You must define key-chord bindings including 1, 2 or 3 but not 4.

Because I define key-chord like @4 and @5, I got the error with negative prefiex -4 or `-5'.

Does this issue fixed with emacs' commit https://lists.gnu.org/archive/html/emacs-diffs/2015-02/msg00425.html ?

I don't have emacs-trunk environment :-(
