Comment (by nomeata):

 I occasionally have that as well; right now in `library/base`:
 {{{
   HC [stage 1] libraries/base/dist-install/build/Control/Applicative.o
 ghc-stage1: panic! (the 'impossible' happened)
   (GHC version 7.9.20140129 for x86_64-unknown-linux):
         tcIfaceGlobal (local): not found:
     base:Control.Applicative.$fApplicativeWrappedMonad{v ri}
     [(0c7, Identifier ‛base:Control.Applicative.<*>{v 0c7}’),
      (0c8, Identifier ‛base:Control.Applicative.pure{v 0c8}’),
      (0c9, Class ‛base:Control.Applicative.Alternative{tc 0c9}’),
 ...
 }}}

 Thorough cleaning helps. Sorry, no further clues.
