Create a single-line file x.hs with contents
{-# LANGUAGE -FlexibleInstances #-}
And run ghci x.hs.
GHCi, version 6.10.4: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done. Loading package integer ... linking ... done. Loading package base ... linking ... done. ghc: panic! (the 'impossible' happened)
(GHC version 6.10.4 for i386-unknown-linux):
getOptions'.parseLanguage(2) went past eof token
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
If the dash is removed, {-# LANGUAGE FlexibleInstances #-} the file parses properly.
