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).

 Simon
