What was the architecture of the system on which you ran the command "guix build --target=powerpc64-linux-gnu bootstrap-tarballs"? That may help me reproduce the issue. Can you remind me why bootstrap-tarballs uses Guile 2.2? Is there any possibility we can use Guile 3 instead? Maybe doing so could work around this problem. Or maybe I'm just confused. :-) It sounds like you're saying that one could reproduce this issue by doing the following: - Do a "guix pull" to install Guix commit f47e761a10675b05b07107035d5024618267a3ad (from your repo). - Use this newly pulled Guix to build the bootstrap binaries: guix build --target=powerpc64-linux-gnu bootstrap-tarballs - This should produce the same binaries that are found here: https://gitlab.com/lle-bout/guix-bootstrap/-/commit/8e464405c0ba76b29e11c3b60af4d6ea9c83c188 - Update the Guix source so that Guix will use those newly built bootstrap binaries (it looks like you did this in commit bb7d8f3b2ec469c6b3f460e4731871e8e2314dc4 in your repo). - On a POWER9 machine, get the new Guix source (e.g., commit bb7d8f3b2ec469c6b3f460e4731871e8e2314dc4 from your repo), and build Guix from source using the foreign distribution's native libraries (i.e., build Guix without using Guix, since it isn't available yet on POWER9). - Once you've built Guix in your local checkout, run "./pre-inst-env guix build hello" to observe the crash. Is that basically right? I will try to reproduce this and poke at it a bit. Please let me know if I have misunderstood anything. -- Chris
