Yes, done: <https://bugs.gnu.org/28211>.

I took a look: the code in (guix build graft) is multi-threaded but
there’s no shared state among threads (except for the current
output/error ports, which may partly explain the error messages that
suggest memory corruption.)  So it may be that the problem is in
libguile.
