I’ve pushed a workaround here:

  
https://git.savannah.gnu.org/cgit/guix.git/commit/?id=8446dc5a360e3a13fecea870f86efdbd893e3905

and guix-0.14.0-8.bc880f9 includes that fix.

It’s been running for several hours on berlin, building a bunch of
things notably on aarch64, and it seems to work well!

On the Guix side this can be considered fixed, I think.

On the Guile side, we’ll have to push the fix for
<https://bugs.gnu.org/30368>.
