#11715: There's something fishy going on with Constraint -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: high | Milestone: 8.0.1 Component: Compiler (Type | Version: 8.0.1-rc1 checker) | 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 bgamari): So I believe that the culprit lies somewhere in the simplifier since the `dump-ds` output looks reasonable but `dump-simpl` reveals that the `Typeable Proxy` dictionary has been floated to the top level and has been applied to either `*` or `Constraint`, depending upon the order of the `print` statements, and that the same dictionary is used in both `print`s. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11715#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
