What about giving them =E2=80=9Cguix pack mrustc=E2=80=9D, or a guix-instal= l.sh + pull command sequence, or a VM image? The instructions would be: 1. Download and run . It will perform the steps described at . 2. Write this to a file: (list (channel (name 'guix) (url "https://git.savannah.gnu.org/git/guix.git") (commit "0b2ea78173f05c417a9002e52e2b36b139074124"))) 3. Run =E2=80=98guix pull -C that-file.scm -p ~/core-updates=E2=80=99. 4. Run =E2=80=98~/core-updates/bin/guix build rust -s i686-linux -K=E2=80= =99. Investigate as per . Perhaps you could propose them to do that, and if that=E2=80=99s too much to ask, we can meet halfway somehow. Of course we can also provide guidance on #guix on IRC.

Would Valgrind or ASan be able to flag the potential issue? Thanks, Ludo=E2=80=99.
