Guix is failing to build on core-updates for x86_64-linux:

https://hydra.gnu.org/job/gnu/core-updates/guix-0.12.0-5.1162.x86_64-linux

I can't reproduce this failure on my own machines.

Here is the backtrace, which has now been reproduced 3 times on the
build machines:

------

There is also some interesting garbled text earlier in the logs.
