I think this bug was fixed in Guix in February:

https://git.savannah.gnu.org/cgit/guix.git/commit/?id=78bbf6c44394c1024e0a369d0d5947e669606248

If I understand correctly, you're trying to use Guix from May 2020.

I recommend trying again but with "--cores=1" [0]. The lz4 test suite may
not support multithreaded execution reliably:

https://github.com/lz4/lz4/issues/957

You can limit the use of a single thread by only building this lz4
derivation with --cores=1:

`guix build /gnu/store/8r1d8lw4xix0r90irz0rr1gnnq4mainz-lz4-1.9.3.drv --cores=1`
