But without the coverage flag it’s OK.

I found it when switching from 7.6.3 to 7.8.1RC2 on a project I have and was able to strip it to this: https://github.com/fmaste/ghc-7.8.0.20140228-enable-library-coverage

Don’t know if this is a cabal or ghc problem and I don’t know how to continue.

Thanks!

Found the problem, I did not have the modules that were used but not exposed enumerated under "other-modules” on cabal's library definition. This builds OK on 7.6.3 even with a correct code coverage report, but fails to build with the linking error under 7.8-rc2. When I add the “other-modules” it works on both.
