#14880: GHC panic: updateRole -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: goldfire Type: bug | Status: new Priority: normal | Milestone: 8.6.2 Component: Compiler (Type | Version: 8.2.2 checker) | Resolution: | Keywords: TypeInType Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash or panic | Test Case: Blocked By: | Blocking: 15592 Related Tickets: #15076 | Differential Rev(s): Phab:D4769, Wiki Page: | Phab:D5141, Phab:D5147, Phab:D5150 -------------------------------------+------------------------------------- Comment (by goldfire): Interestingly, the current approach to this undoes the work to fix #14552, which has a very similar character. We now accept the program in #14552, but zapping some tyvars to `Any` (an approach we recognized would work back then, but decided issuing an error was better).
