GHC panics if closing #-} for a LANGUAGE pragma is not on the same line
This came up on #haskell:
{-#
LANGUAGE ExistentialQuantification
#-}
main = undefined
This sends ghc-6.10.3 into a tailspin:
$ ghc --make foo.hs
ghc: panic! (the 'impossible' happened)
(GHC version 6.10.3 for x86_64-unknown-linux):
getOptions'.parseLanguage(1) went past eof token
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
Moving the #-} onto the LANGUAGE line fixes this.
