Thanks, looks like it's option (1) then. Could you tell me what Haskell type I have to use be able to pass a pointer to this binary to C land (genuine address, not StablePtr). I don't think the standard FFI allows this at all but, IIRC, the old ghc libraries allowed you to do this with a mutable byte array.
