Hello,

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

--8<---------------cut here---------------start------------->8---
$ 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
--8<---------------cut here---------------end--------------->8---

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.
