GHC-8.0.0.20160109 runs into "Bad interface file: ... Something is amiss"

When I first started testing GHC-8.0.0.20160109 I could compile a lot of packages. However, now I get the following error more and more frequently:

$ cabal install --with-ghc=ghc-8.0.0.20160109 --with-haddock=haddock-ghc-8.0.0.20160109 http://hackage.haskell.org/package/set-cover-0.0.8/set-cover-0.0.8.tar.gz
