Comment (by AlexanderThiemann):

 I get this error when trying to run my test-suite:

 I think I am stumbling over the issue on both GHC7.6 and GHC7.8. I'm not
 sure how I can create a smaller test case, so I'll just point you to the
 commit and the travis build:

 https://github.com/agrafix/Spock/tree/575fdb1332b719a23d84e1fbb67f097f22d64e68
 https://travis-ci.org/agrafix/Spock/builds/36477042

 cabal clean "solves" the issue...
