#13658: Assertion failure on HEAD: "optCoercion changed types!" -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: new Priority: high | Milestone: 8.2.1 Component: Compiler | Version: 8.3 Resolution: | Keywords: 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 slyfox): I've added a bit of debug into ASSERT. The complain is about type mismatch between in_ty1, out_ty1: {{{ in_ty1: base:Data.Typeable.Internal.TypeRep{tc 35W} (ghc-prim:GHC.Types.Any{(w) tc 35K} ghc-prim:GHC.Types.Any{(w) tc 35K}) out_ty1: base:Data.Typeable.Internal.TypeRep{tc 35W} ghc-prim:GHC.Types.Any{(w) tc 35K} }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13658#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
