Comment:

 This is a Cabal bug: https://github.com/haskell/cabal/issues/2982

 Later reported duplicate: https://ghc.haskell.org/trac/ghc/ticket/9009

 GHC is not really in the business of checking the well-formedness of
 archive files installed in the package database, so there is not much GHC
 can do here.
