Closing under the premise that it in fact disappeared :)

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

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 > Such an overflow normally won’t happen unless you try to preload > additional libraries or add features to the standard ones. Is there anything noteworthy going on in stuff like LD_PRELOAD? Regards, Liliana

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
