The tests for doctest are not passed again with GHC 7.8:

17) Property.runProperty reports the values for which a property that takes multiple arguments fails
expected: ["False","0","\"\""]
 but got: ["<interactive>:24:66:","    \8216doctest_prop\8217 is not in the type environment at a reify","    In the splice: $(polyQuickCheck 'doctest_prop)"]

This comes from:

    quickCheck term vars =
      "let doctest_prop " ++ unwords vars ++ " = " ++ term ++
      " in $(polyQuickCheck 'doctest_prop)"

It seems to me that the behavior of GHC 7.8's Template Haskell
changed. Would you tell me how to fix this?
