 GHC failed when trying to build stack from source on MacOS 10.12 using GHC
 8.0.1.

 The relevant part of the error is here:

 Full build logs (includes dependency installation via cabal-install):
 https://gist.github.com/8e005710eab17139c02267bac3029e33

 This occurred when installing stack, but reporting here because of the
 "Please report this as a GHC bug" message in the failed build output.
