You're trying to coerce a state token to ByteArray#.
Which is certainly a bad thing to do. I wonder if we can produce a more civilised error, from Core Lint, perhaps? We should not unsafely coerce between types with different representations, and that might not be too hard to spot. Just by looking at the kind of the two types. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15128#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
