[Template-haskell] reifyDecl problem

[Dmitry Malenko]

Hi, All!

In test code given below trying to reifyDecl function or constant
declaration couse GHC to panic. Both CVS HEAD and 6.0.

Am I mising something in reification of function declarations or is this
reakky a bug in GHC?

[dima@farside tmp]$ ghc --make -fglasgow-exts Main.hs 
Chasing modules from: Main.hs
Compiling Main             ( ./Main.hs, ./Main.o )
ghc-6.1: panic! (the `impossible' happened, GHC version 6.1):
        dsReify reifyDecl Main.l {- v rcA -}

Please report it as a compiler bug to glasgow-haskell-bugs@haskell.org,
or http://sourceforge.net/projects/ghc/.

[dima@farside tmp]$ ghc-6.0 --make -fglasgow-exts Main.hs 
Chasing modules from: Main.hs
Compiling Main             ( Main.hs, ./Main.o )
ghc-6.0: panic! (the `impossible' happened, GHC version 6.0):
        dsReify reifyDecl Main.l {- v rcz -}

Please report it as a compiler bug to glasgow-haskell-bugs@haskell.org,
or http://sourceforge.net/projects/ghc/.

\begin{code}
import IO
import Language.Haskell.THSyntax

data T = A String | B

l = A "kuku"

f x = x

k = reifyDecl l

main :: IO ()
main = do x <- unQ k
          putStrLn (show x)
\end{code}
