#8853: Surprising mention of unboxed integers in pattern exhaustiveness warning -------------------------------------------------+------------------------- Reporter: MikolajKonarski | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: Resolution: | 7.8.1-rc2 Operating System: Linux | Keywords: Type of failure: Incorrect warning at | Architecture: compile-time | x86_64 (amd64) Test Case: | Difficulty: Blocking: | Unknown | Blocked By: | Related Tickets: -------------------------------------------------+------------------------- Comment (by nomeata):
To be clear, the error message is alarming because it refers to unboxed integers, but the source code does not.
Ok, that was my guess as well, adjusting ticket title (unfortunately, I can’t change the ticket body to remove the distracting runtime output). I agree that the compiler would ideally not talk about unboxed integers if the code is not. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8853#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
