#10946: Typed hole inside typed Template Haskell bracket causes panic -------------------------------------+------------------------------------- Reporter: jstolarek | Owner: Type: bug | Status: new Priority: high | Milestone: 8.0.1 Component: Template Haskell | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): -------------------------------------+------------------------------------- Comment (by jstolarek): This error is raised in `TcErrors.getSkolemInfo` called from `TcErrors.mkHoleError`. Quick look at the code tells me that "implication constraints" are expected to be non-empty but they are. Are implication constraints things that come in the contexts, ie. everything before a `=>`? Why are they expected to be non-empty? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10946#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
