#15370: Typed hole panic on GHC 8.6 (tcTyVarDetails) -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: Tritlo Type: bug | Status: merge Priority: high | Milestone: 8.6.1 Component: Compiler (Type | Version: 8.4.3 checker) | Keywords: TypeInType, Resolution: | TypedHoles Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by Tritlo): bgamari: It appears that the changes in b202e7a48401bd8e805a92dcfe5ea059cbd8e41c are not yet merged. If you merge that to `ghc-8.6`, it fixes the panic in `T15370`, and then https://phabricator.haskell.org/D5004 fixes the assertion that was being violated in `DEBUG`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15370#comment:17 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
