Comment:
Thank you for investigating this. It looks as if my hypothesis was right:
Cabal is causing you to (a) compile a module against M.hi, but then (b)
link against an M.o that was generated by a different call of GHC. That's
simply not supported by GHC: .hi and .o files are indissolubly bound
together.
So I declare this a Cabal bug. Antoine has helpfully opened a Cabal
ticket for it
http://hackage.haskell.org/trac/hackage/ticket/624, so I'll close this one
as "invalid" (ie not GHC's problem).
