incorrect pragma syntax leeds to panic

[zickzackv]

When using a wrong pragma syntax like:

{-# LANGUAGE IncoherentInstances? -#} {-# LANGUAGE OverlappingInstances? #-} -- wrong pragma syntax! {-# LANGUAGE NoMonomorphismRestriction? #-} {-# LANGUAGE MultiParamTypeClasses? #-}

This leeds to the following ghc panic:

ghc: panic! (the 'impossible' happened)

(GHC version 6.10.4 for x86_64-apple-darwin):

getOptions'.parseLanguage(1) went past eof token

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