Indeed this sounds like a real bug. Can you open a ticket?

Also, it looks like the gist has projected out directory structure; do
you think you could push the testcase as a proper git repository?

The problem is that we don't have access to cabal-install. However,
I think there is certainly room for this sort of testing as part of, for
instance, the nightly test cycle. In this case we'd likely want to
contain this infrastructure in a repository outside of ghc proper.
