Subject: 24.0.92; quiting erc causes crash
Date: Sun, 22 Jan 2012 23:07:01 +0100

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgement at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

I run the following code when quitting emacs:

(defun ivan-erc-stop ()
  "Turn off ERC."
  (interactive)
  (when (fboundp 'erc-cmd-GQUIT)
    (erc-cmd-GQUIT "")
    (dolist (ies-buf (buffer-list))
      (when (eq (buffer-local-value 'major-mode ies-buf) 'erc-mode)
        (kill-buffer ies-buf)))))

I often get the following crash:

Hi,

I am still experiencing this bug from time to time.

I have a workaround to save my files before disconnecting erc.

The reasonable thing to do would be to ignore it. However I am not
reasonable ;) When the crash happens I land in gdb, can I do something
else than looking at the backtrace to help nailing this bug?

Note that I removed emacs-devel from the CC list: there's no need to
discuss bug reports on that list, it just confuses people and the bug
tracker.

Well, how about if you start by telling what kind of "crash" was that?
GDB normally says something like "Program received signal SIGFOO, ...".
What was the signal in your case, please?  In general, please post
everything GDB displays at the point of crash, before it displays its
"(gdb)" prompt (at which you types "bt full").

Also, please start GDB from the Emacs's src/ directory, so that the
backtrace includes the Lisp-level backtrace, and also some very
helpful commands are available for displaying Lisp data types.

OK, who am I supposed to talk to when a bug is left alone?

Will do next time it crashes.

You send a ping to the bug address.  It will be automatically
reflected to the bug-gnu-emacs mailing list, to which all Emacs
maintainers and developers subscribe.

Including the last time it crashed?  If so, how come there was no Lisp
backtrace at the end of the C-level backtrace you sent?

AFAIK, SIGPIPE means that the other side of the pipe was closed.  Is
Emacs communicating with a program or with the network directly?  If
the former, please see why does the program exit; if the latter,
perhaps you have connectivity problems?

Correct if I am wrong, ERC is communicating directly with the network. I
don't have connectivity problem. This bug only happens when I shut down
emacs. To make things trickier, it doesn't happen all the time :(

Sorry, I forgot that.  So perhaps it's Emacs that shuts down the
connection too early, and then ERC tries to communicate?

Timing issues?

Anyway, I'm talking way past my pay grade here.  Perhaps someone else
will have a clue that I don't.

Hi,

I think the default behavior of gdb is to simply stop on SIGPIPE, even
though emacs might have handled the signal just fine.

Maybe you could try issuing this command to gdb, before starting emacs:

handle SIGPIPE nostop

and see if there still is a problem.

(And maybe that command should go into in .gdbinit (?))

Regards
Troels

It works, thanks!

It probably should...

So IIUC, there is no Emacs bug here; it's all a side effect of running
Emacs under gdb? And the suggestion is to add the SIGPIPE line to
Emacs's .gdbinit? I can't comment on whether that is a good idea or not;
hopefully others will.

Yes

I am not suggesting anything. I have setup my environment as Troels has
suggested.

I have no idea either.
