Does that look sensible to you? Also, reproduction instructions which use stack are not useful as it is not easy to use a custom build of GHC with stack. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12604#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I am very new to haskell. If you will advice me what to do, I would like to do it. I can attach my source code, which is like 50 lines. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12604#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

It is two files. 1. `M.hs` {{{ {-# LANGUAGE TypeFamilies #-} module M ( -- * Abstract array representation Array (..) , Source(..) ) where class Source r where data Array r data C instance Source C where data Array C = ACursored { cursoredExtent :: Int } }}} 2. `Test.hs` {{{ module Test where import M (Array) }}} Reproduce with `ghc Test.hs`. Error being {{{ ghc: panic!
