#11580: panic on incompatible options -------------------------------------+------------------------------------- Reporter: dougm | Owner: Type: bug | Status: merge Priority: low | Milestone: 8.0.1 Component: Compiler | Version: 7.8.4 Resolution: | Keywords: newcomer Operating System: Linux | Architecture: x86_64 Type of failure: Compile-time | (amd64) crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D1925 Wiki Page: | -------------------------------------+------------------------------------- Comment (by rwbarton): For anyone else who was confused at first like me, the panic actually arises from specifying all ''three'' of `-XSafe`, `-XUnsafe` and `-XTrustworthy` because then the result of combining the first two flags is demanded when adding the third flag. We should still add * a test for `-XSafe -XUnsafe -XTrustworthy` (under `safeHaskell/flags`; I'm not going to do it right now just because I would have to build ghc to find out what the right error message is) * the original test in this ticket * possibly other versions of that test for the `-d`, `-f` and `-W` flags. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11580#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
