#11665: Recent master fails to build attoparsec-0.13.0.1 with core lint failure ---------------------------------------+--------------------------------- Reporter: anton.dessiatov | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.1 Keywords: | Operating System: Linux Architecture: x86_64 (amd64) | Type of failure: None/Unknown Test Case: | Blocked By: Blocking: | Related Tickets: 11664 Differential Rev(s): | Wiki Page: ---------------------------------------+--------------------------------- You might also like to see #11664 for some history. I have tried using current `master` 57b4c5524fcbf02f61dfc8d9395906dc7f50f048 to build current `attoparsec-0.13.0.1` on Ubuntu Linux 15.10 x86_64. The build fails with Core Lint error {{{ <no location info>: warning: In the type ‘Buffer -> Pos -> More -> a_aOwS -> IResult Text r_aOwT’ @ a_aOwS is out of scope }}} Attached comes full output of `cabal install attoparsec --with-ghc=<path- to-ghc> --verbose --ghc-options -dcore-lint`. The output is huge (57k lines) so I gzipped it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11665 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
