#13981: Family instance consistency checks happens too early when hs-boot defined type occurs on LHS -------------------------------------+------------------------------------- Reporter: ezyang | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.4.1 Component: Compiler (Type | Version: 8.2.1-rc2 checker) | Resolution: | Keywords: hs-boot Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by inaki): OK, I managed to minimize the problem, it seems to be indeed related to type families. I have filed a separate issue, but perhaps it is the same thing as in this one: #14080. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13981#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
