#15569: Constant folding optimises 1 into 3 -------------------------------------+------------------------------------- Reporter: snowleopard | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.6.1 Component: Compiler | Version: 8.6.1-beta1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #9136 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by snowleopard): Here is a quick fix: https://phabricator.haskell.org/D5109. Adding the above example as a single test and closing this ticket seems a bit unsatisfactory. I think we need to either 1) do some automated correctness checking or 2) refactor the code so that it's more obvious that there are no remaining bugs. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15569#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
