Loading this module causes panic in interpreter.

[jsnx]

This file causes a panic when I try to load it in ghci; but it compiles okay with ghc.

Loading package ghc-prim ... linking ... done.
Loading package integer ... linking ... done.
Loading package base ... linking ... done.
Prelude> :load Submutations.hs 
[1 of 1] Compiling Submutations     ( Submutations.hs, interpreted )
ghc: panic! (the 'impossible' happened)
  (GHC version 6.10.4 for i386-apple-darwin):
        schemeE(AnnCase).my_discr __word 0

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

This bug has been observed with 6.10.3 on OS X and 6.10.4 on both OS X and x86_64 Linux.

When the definition of permutations is commented out and replaced with undefined, the problem goes away.

Thanks for the report. This is a duplicate of #2881, so I'll close this ticket.

No, I guess not -- #2881 has to do with pattern matches on Word.
