Hi David, The issue you are having seems related to https://github.com/golang/go/issues/16636
I'm also running Arch Linux, and it seems like -fsanitize=memory is broken on general for Clang on Arch. Would you be able to verify if this is also the case for you? Add a comment to the issue, rather than this thread to keep the discussion on track.
