impossible happened: splitTyConApp a{tv i6hr}

[Frederik Eaton]

Here's another example of the same bug:

----------------------------------------------------------------
$ ghc -O3 -threaded -package Futility --make scmp.hs -o scmp && install scmp ~/bin/
Chasing modules from: scmp.hs
Skipping  Engines          ( ./Engines.hs, ./Engines.o )
Skipping  SCmp             ( ./SCmp.hs, ./SCmp.o )
Compiling Fitting          ( ./Fitting.hs, ./Fitting.o )
ghc-6.4.2: panic! (the `impossible' happened, GHC version 6.4.2):
        splitTyConApp a{tv a8OQ}

Please report this as a compiler bug.  See:
  http://www.haskell.org/ghc/reportabug

It's also linked to my GSLHaskell2 library which is still exhibiting
the bug.
