#9440: Buggy binder swap in occurrence analysis -------------------------------------+------------------------------------- Reporter: afarmer | Owner: Type: bug | Status: patch Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: | Blocked By: None/Unknown | Related Tickets: Test Case: | Blocking: | Differential Revisions: Phab:D156 | -------------------------------------+------------------------------------- Comment (by afarmer): (a) turned out to be easy enough, I just tagged the binders before checking for usage in the alt. (b) and the coercion variables required a slight bit of refactoring. See the Phab:D156 patch for details. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9440#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
