ghc needs to be compiled with BuildVlavour = devel2
Which exact version of GHC are you building? Can you try with the `ghc-8.0` branch? I don't get this assertion failure when compiling the module you give above; and it might well have been fixed. Is this a show-stopper for you? This particular assertion failure is almost certainly not a problem; we should fix it (that's why it's there) but it probably won't cause any problems. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12760#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
