building hashed-storage 0.4.3: Expected one of wanted constraints (BUG)
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.
