Hello,
On the 'core-updates-frozen' branch, attempting to pull 'master' gives a

I bisected it down to cb06f7c61e4b:
commit cb06f7c61e4b8393abf38f1f5891e03c33d53b9b
Author: Ludovic Courtès <ludo@gnu.org>
Date: Thu Sep 9 23:22:10 2021 +0200
base32: Provide an open-coded 'bit-field'.
This improves the throughput of 'bytevector->base32-string' a bit.
* guix/base32.scm (bit-field): New macro.
It can be reproduced with a two-dimensional time machine:
$ guix time-machine --branch=core-updates-frozen -- time-machine \
--commit=cb06f7c61e4b8393abf38f1f5891e03c33d53b9b -- build hello
...or by pulling 'core-updates-frozen' and attempting to pull 'master'.
The commit was merged to 'core-updates-frozen' in 5c3cb22c9b281066, so
pulling core-updates-frozen -> core-updates-frozen also fails in a
similar manner (albeit on a different derivation).
