Description

Using GHC 7.0.1-rc1 with the patch for trac#4345, while compiling Storage.Hashed.Monad from version 0.4.3 of the hashed-storage package I get the following message:

ghc: panic! (the 'impossible' happened)
  (GHC version 7.0.0 for i386-unknown-linux):
        Expected one of wanted constraints (BUG)

This is from http://hackage.haskell.org/package/hashed-storage-0.4.3. The bug still occurs using the latest version, 0.5.3.

I believe this is already fixed in the HEAD. Can you try with that? Or await RC2, and try then. Thanks.

I wasn't able to build HEAD - it said it couldn't make utils/runghc/runghc.cabal, due to an Oct 6 patch. I'll try backing out some patches.
