GHCi crash on invalid input

    • Closed Issue created by aslpavel @trac-aslpavel

    I know its incorrect haskell code but after entering following sequence of commands, ghci seems to be crashing.

    GHCi, version 7.6.3: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
 λ > data R = R { x1 :: Int, x2 :: Int, x3 :: Int } deriving Show
 λ > data R a = State { x1 :: Int, x2 :: Int, x3 :: Int } a
ghc: panic! (the 'impossible' happened)
  (GHC version 7.6.3 for x86_64-unknown-linux):

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

    I hope it would be helpful. Thanks!
