Hi,

since http://git.haskell.org/ghc.git/commitdiff/1946922c61df427e59f8a00572fd4dd650... travis is complaining:

Does anyone have an idea what may be causing this?

A bit more context here is haddock started too early:

I guess real fault is: http://ghc.haskell.org/trac/ghc/changeset/f31b042c25b9c51efdbe84c1cb6f65f495...

Or not. Looks like it's easy to reproduce as: $ make libraries/base/dist-install/build/Data/Coerce.o V=1 What is more interesting: ghc/libraries/base/Unsafe/Coerce.hs:

import GHC.Integer () -- for build ordering

Attached patch fixes the error, but I have no idea why. Maybe, NoImplicitPrelude is not enough and some types leak in here? Maybe Ian (CCed) remembers the story.

Fix build order when building with integer-simple

The problem hasn't shown up with integer-gmp, but I can't see why it couldn't happen in that case too.

Ah. The reason that Data.Coerce looks for the interface for GHC.Integer.Type is because TidyPgm expands integer literals using 'mkInteger' from that module, and TidyPgm always does the lookup regardless just in case. There's a hack to switch this off for packages ghc-prim and integer-gmp/simple, but every other compilation will read that interface.
