Comment:

 Maybe I'm inferring too much, looking at the output of ghc 7.10.3:

 {{{
 $ ghci B.hs
 GHCi, version 7.10.3: http://www.haskell.org/ghc/  :? for help

 B.hs:3:23: Warning: {-# SOURCE #-} unnecessary in import of  ‘A’
 [1 of 3] Compiling A[boot]          ( A.hs-boot, interpreted )
 [2 of 3] Compiling A                ( A.hs, interpreted )

 A.hs:6:3: Not in scope: data constructor ‘C’
 Failed, modules loaded: A, A.
 }}}

 I see that two 'A' modules are loaded, the first one probably being the A
 .hs-boot file. So perhaps 'isModuleInterpreted' is not getting "wrong"
 ModSummary, but it is some other type of regression with regards to
 reporting errors when hs-boot files are involved.
