#12056: Too aggressive `-w` option -------------------------------------+------------------------------------- Reporter: asr | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: newcomer Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect | Unknown/Multiple warning at compile-time | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by thomie): * keywords: => newcomer Comment: It looks like this only happens when `-w` is combined with `-Wunrecognised-warning-flags`. GHC seems to do the right thing when using `-w` and some other warning flag (make sure to use `-fforce-recomp` during testing). For a newcomer. The code to change is in `compiler/main/DynFlags.hs`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12056#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
