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).
