Issue created Nov 02, 2008 by Bertram Felgenhauer@int-eReporter

ghc panic with Haskell 98 program (applyTypeToArgs?)

This code,

module Bug where

data S = S { s1 :: (), s2 :: () }

f s = s { s1 = (), s2 = s1 s }

crashes ghc:

ghc: panic! (the 'impossible' happened)
  (GHC version 6.11.20081031 for i386-unknown-linux):
        applyTypeToArgs
    ghc-prim:GHC.Unit.(){(w) v 71} [gid] wild{v sfY} [lid]
    ghc-prim:GHC.Unit.(){(w) tc 40}

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

(Example trimmed down from a compile error in language-c. ghc 6.10 is not affected.)
