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.
