The GHC Windows fast buildbot now fails with:

    ifBuildable/ifBuildable base setup/Setup haddock
    Preprocessing library base-2.1...
    Running Haddock for base-2.1...
    ..\..\utils\ghc-pkg\ghc-pkg-inplace.bat field rts-1.0 haddock-interfaces
    ..\..\utils\ghc-pkg\ghc-pkg-inplace.bat field rts-1.0 haddock-html
    Setup: ../../bootstrapping.Cabal/Distribution/Simple.hs:(422,21)-(424,23):
    Non-exhaustive patterns in case

That's the last 3 lines of:

    let getField pkgId f = do
            let name = showPackageId pkgId
            s <- rawSystemStdout verbose pkgTool ["field", name, f]
            return $ case words s of
                _:v:_ -> v
                [] -> []

so presumably we're getting a single word from ghc-pkg.


Thanks
