TypeApplications: panic from unknown function identifier

    • Closed Issue created by j6carey @j6carey

    Using type application with an unknown function identifier causes ghci to panic:

    $ ghci
GHCi, version 8.0.2: http://www.haskell.org/ghc/  :? for help
Prelude> :set -XDataKinds
Prelude> :set -XTypeApplications
Prelude> foo @3
ghc: panic! (the 'impossible' happened)
  (GHC version 8.0.2 for x86_64-unknown-linux):
	initTc: unsolved constraints
  WC {wc_insol =
        [W] foo_a12q :: t_a12p[tau:1] (CHoleCan: foo)
        [W] foo_a12O :: t_a12N[tau:1] (CHoleCan: foo)}

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