#15552: Infinite loop/panic with an existential type. -------------------------------------+------------------------------------- Reporter: howtonotwin | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.4.3 Resolution: | Keywords: TypeInType, | TypeFamilies Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: #14723 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): Patch looks fine. As for the larger plan: I like all of it, including separating `TcType` from `Type`. Could we also remove `TcTyVar` from the `Var` type? Then we could statically guarantee that no `TcTyVar`s are in Core. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15552#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
