Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.10.4 | Keywords: language pragma
Os: Unknown/Multiple | Testcase:
Architecture: Unknown/Multiple | Failure: Compile-time crash
---------------------------------+------------------------------------------
if the language pragma is closed on a new line panic breaks out.
adding two spaces before the #-} is sufficient to compile.
used 6.10.4 on ubuntu 9.04
here the output and the program:
fr...@atlantaj:~/leksahworkspace/spaceTimeDuality$ ghc panic.hs
ghc: panic! (the 'impossible' happened)
(GHC version 6.10.4 for i386-unknown-linux):
getOptions'.parseLanguage(1) went past eof token
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
----------
the program is:
{-# LANGUAGE TypeSynonymInstances
#-}
module SpaceTimeDuality where
main = do
return ()
