In emacs@27.2, a warning appears about pure storage overflow in the *GNU Emacs*
buffer that displays at startup. My main concern is that I'm not sure if Emacs's
garbage collection is working or not, so I have been hesitant to upgrade from
version 26.3.
Steps to reproduce (with output):
-----8<---begin-snippet---8<--------------------
$ guix environment -C --pure --preserve=TERM --user=foo --no-cwd --ad-hoc emacs
$ emacs -nw --batch --eval="(progn (display-about-screen)(message \"%s\"
(buffer-substring-no-properties 1 122)))"
Warning Warning!!! Pure space overflow !!!Warning Warning
(See the node Pure Storage in the Lisp manual for details.)
-----8<---end-snippet---8<--------------------
I am using Guix on a foreign distribution (Trisquel 9).
$ guix describe
guix 075c9f1
repository URL: https://git.savannah.gnu.org/git/guix.git
branch: master
commit: 075c9f12696d23bc86999b7a9ed567f38715e00a
The corresponding emacs@27.2 store item is
/gnu/store/n1zvyjk8hm51793ap5ikvzvq15lxkhrg-emacs-27.2
$ uname -i
i686

So for me on an x86_64 machine with Guix commit
7628430a2f46a4a57d5ff7e51b1be80b7765c96c, this snippet displays
--8<---------------cut here---------------start------------->8---
This is GNU Emacs, one component of the GNU/Linux operating system.
GNU Emacs 27.2 (build 1, x86_64-pc-linux-gnu, GTK+ V
--8<---------------cut here---------------end--------------->8---
Your version is not that much newer than mine, so it's probably an
issue specific to i686 (or perhaps other non-x86 architectures too).

Liliana

Said node says

Guix-built Emacs uses pdumps since 27.1, so garbage collection should
still be enabled. It might also be worth checking the Guix System vs.
foreign distro angle, as

Is there anything noteworthy going on in stuff like LD_PRELOAD?

Good idea. I've added 'env' to the container. (The aforementioned warning is
unaffected by the presence of coreutils).
$ guix environment -C --pure --preserve=TERM --user=foo --no-cwd --ad-hoc emacs

Hi all,
The pure space overflow warning does not appear in emacs-next@28.0.50-0.2ea3466
on my i686 machine, so this bug will disappear when the emacs package definition catches up to emacs-next.
Happy hacking,
Calvin

Closing under the premise that it in fact disappeared :)
