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

Found on the latest staging branch. The diffoscope log produced by:

--8<---------------cut here---------------start------------->8---
diffoscope --exclude-command '/gnu/store/.*/bin/stat' --text=emacs.diffoscope /gnu/store/cjmgl8820dhxb400q9zv90b1a1z0px14-emacs-26.1{,-check}
--8<---------------cut here---------------end--------------->8---

The 'stat' command output was muted to ignore the many occurrences of
differing link numbers (and reduce the attached log size).

Here's an excerpt:

Dear,

An update to say that the situation is maybe worse.


Let build the same version than Ludo [1] with:

--8<---------------cut here---------------start------------->8---
guix time-machine --commit=f678cc9 -- build emacs
guix time-machine --commit=f678cc9 -- build emacs \

diff -r --no-dereference
/gnu/store/zja4gdq52wxlppa0pq2j5id7pl9zfqkq-emacs-26.3{,-check}
--8<---------------cut here---------------end--------------->8---

[1] https://debbugs.gnu.org/cgi/bugreport.cgi?bug=35085#8


Then, Ludo reported theses ones that I do not have:

--8<---------------cut here---------------start------------->8---
lisp/calendar/cal-iso.elc
lisp/cedet/semantic/lex-spp.elc
lisp/cedet/semantic/tag-ls.elc
lisp/emacs-lisp/easy-mode.elc
lisp/eshell/esh-proc.elc
lisp/vc/ediff-mult.elc
--8<---------------cut here---------------end--------------->8---

but instead I have these ones:

And building several times changes a bit this list, e.g., sometimes
'lisp/progmodes/ada-xref.elc' differs, sometimes not.


Using Guix commit 3c9e86ae8bf09d993e2e7a4ecb43d80da8fabb99, * means
appears in the Ludo's list and # in mine (above).

--8<---------------cut here---------------end--------------->8---

For example, the file 'lisp/cedet/semantic/lex-spp.elc' sometimes
differs, sometimes not.


Maybe, the first step is to inspect the .elc files. But I am not sure
how to use diffoscope, I mean, I am not able to find my road with:

--8<---------------cut here---------------start------------->8---
diffoscope /gnu/store/54m1fqnkhjm5jy22barxy3r86jg6nsxs-emacs-26.3{,-check}/share/emacs/26.3/lisp/emacs-lisp/easy-mmode.elc
--8<---------------cut here---------------end--------------->8---



All the best,

Hi,

I filed a duplicate bug earlier today while working on emacs-next. The 
problem now also seems to include the new .pdmp files.

Best,

Not sure if this is good of bad news, though.

The good news:

Let see if there is an upstream willing to tackle this. :-)

Hi Aaron,

I see that you've cancelled the talk on EmacsConf 2024, is there a place
where we can find information on the subject? We want to tackle this in
Guix and despite using `--disable-build-details`, the profile dump is
still unreproducible on emacs <at> 30.1.

Thanks!

I think you should take a look at the work done by Bernhard M. Wiedemann:
