It's actually b8b3e30a6eedf9f213b8a718573c4827cfa230ba (Axe RecFlag on TyCons.) I don't know if this change directly fixes the issue or if it's just a happy coincidence (ezyang, any thoughts?), but either way, I've added a regression test in Phab:D3404. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7944#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
