    ghc: panic! (the 'impossible' happened)
  (GHC version 7.8.3 for x86_64-apple-darwin):
  Simplifier ticks exhausted
    When trying UnfoldingDone base:GHC.Num.$fNumInt_$c+{v rf9} [gid]
    To increase the limit, use -fsimpl-tick-factor=N (default 100)
    If you need to do this, let GHC HQ know, and what factor you needed
    To see detailed counts use -ddump-simpl-stats
    Total ticks: 44020
