I think there are two things fishy here:

  1. What version of guix-daemon is running on your machine?

     The fact that the build directory is called “/tmp/nix-build-…”
     suggests it dates back to before commit 7a57c96a (Dec. 2015.)

  2. What file system is /tmp on?  Presumably a FUSE thing?  This seems
     to be leaking details through the build environment, which may
     explain the GC-related test failures.

> tests/store.scm:156: FAIL dead path can be explicitly collected

This test is just:

    (let-values (((paths freed) (delete-paths %store (list p))))
      (and (equal? paths (list p))
           (> freed 0)
           (not (file-exists? p))))

I expect that maybe (file-exists? p) returns #t for some weird
file-system reason.
