Hello,

Using Guix from both the ‘master’ branch¹ and from the ‘core-updates-frozen’
branch², the following command fails:

Toggle snippet (6 lines)
$ guix build --check \
-e '(@@ (gnu packages commencement) gcc-core-mesboot1)’
⋮
guix build: erro: derivation `/gnu/store/qbnxfv7v7288iisl44kccz68k0pv9qdi-gcc-core-mesboot1-4.6.4.drv' may not be deterministic: output `/gnu/store/rn3qvn67nraicabvlrx1rhw6nsjrpgpx-gcc-core-mesboot1-4.6.4' differs

During the stripping phase, there are many of these warnings, which may be
related:

This was discussed in https://issues.guix.gnu.org/45962. There’s the
beginning of a patch there that needs to be adapted to avoid depending
on xz at this early stage, I think.

Thanks,

Thank you for mentioning that discussion. I should have found that before
filing this issue. Sorry for the duplicate report.
