Normally ‘guix pull’ is deterministic so attempts to build commit
bfa47f14b1a19150d6ddf149597d16493f69ae6d should either fail or succeed,
but that should be reproducible (FWIW I just tried “guix pull
--commit=bfa47f14b1a19150d6ddf149597d16493f69ae6d” and it works for me.)

In the future, if the problem shows up again, could you please post the
‘guix pull’ output that precedes the “You found a bug” error message?

Thanks,
Ludo’.
