Guix,

Follow gdb output on core dump when emacs crash returning error 6.

I might have found a way to work around the issue, I don't know if it
solves the real problem, but might work for you.

See the message I wrote in [1].

The problem is in GTK modules with Emacs. I installed the 
emacs-no-x-toolkit and it works.

Re: emacs-25.3 aborted

[Ricardo Wurmus]

I can reproduce this on i686.  After installing Emacs with “guix package
--no-grafts -u emacs”, however, there is no crash.

The crash only happens with the grafted Emacs.

And indeed --no-grafts doesn’t have this problem.

Could it be that grafting breaks the unexec’d image in subtle ways?

I don't know what caused this, but something between Guix
0.14.0-6.0dcf675 and 0.14.0-8.bc880f9 forced my own computer attempt to
build Emacs, and resulted in a working Emacs version.

Store path name differences for Emacs:

Weird, but thanks for letting us know!

On IRC people have reported Emacs crashes similar to what you had
recently, so it may be that there’s still an issue lurking.

I installed emacs with "--no-grafts" and emacs-exwm with this flag and

Be aware that using --no-grafts means that the resulting Emacs lacks
many security fixes:

  https://www.gnu.org/software/guix/manual/html_node/Security-Updates.html

Thus it’s not a proper solution.

Yes, I agree because it isn't better solution. I'm using it now, but 
I'll study more to fix and I'll send a patch.

Guixs,

I updated my GuixSD and I'm use EXWM + Emacs like my desktop. So, in 
version 25.3 of Emacs there's error when start it in X11 or console 
(TTY). This error only appear in Emacs full installation but I did a 
test using emacs-no-x and it work. Maybe there are a bug with GTK module 
or other dependencies. Someone is there the same error?

Thanks,

Re: emacs-25.3 aborted

[Adonay Felipe Nogueira]

There is a related item in help-guix ([1]), and there was an attempt made
by me to get a backtrace and a strace --- although I still have to find
out how to install debug symbols for GNU Emacs.

As I replied there ([2]), it might be due to a change between
2017-10-10T08:25 BRT and 2017-10-30T16:27 BRST --- either in a Guix
package definition or in the upstreams.

I assume all packages are suspects, but I see that it might be an issue
related to GTK+, or some related component that is present at build
time.

One could list commits from these dates by doing:

--8<---------------cut here---------------start------------->8---
git log --after="2017-10-10T08:25 BRT" --before="2017-10-30T16:27 BRST"
--8<---------------cut here---------------end--------------->8---

Now we must test by making local copies of the possibly affected package
definitions, reverting the commits, and building our Emacs locally.

I'll also post a message similar to this in the thread referenced in
[1].

[1] <https://lists.gnu.org/archive/html/help-guix/2017-11/msg00054.html>.

There are 673 commits here.  Could you attempt a bisect, or manually
reduce the search space by trying out Emacs from earlier commits?

If you have a Guix checkout, just checkout a commit from, say,
Oct. 20th, run ‘make’, and check whether Emacs built from that commit
has the problem:

  guix environment --ad-hoc emacs -- emacs -Q

TIA!

Ludo’.
