Comment (by duog):

 I am working on github/haskell/cabal commit
 0b5f13d71e3282df03495e1db75cd8375b0879ab

 I believe I have not been testing with rc2, but various releases from the
 rc2 branch obtained from https://launchpad.net/~hvr/+archive/ubuntu/ghc.
 I replicated this again with ghc-8.2.0.20170521.

 I am running ubuntu 16.04 with all my packages upgraded.
