#10688: Incorrect program produced, different result with equivalent code -------------------------------------+------------------------------------- Reporter: Ideophage | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.1 Keywords: | Operating System: Linux Architecture: | Type of failure: Incorrect result Unknown/Multiple | at runtime Test Case: | Blocked By: Blocking: | Related Tickets: Differential Revisions: | -------------------------------------+------------------------------------- The program enters an infinite loop (100% cpu, not stopping) because it fails to recognize the stopping condition of a takeWhile. If we make the list finite, it takes all the elements while it should stop before. I don't know how to simplify the code since if I change it a little (e.g. by replacing the name of an object by its definition), sometimes it works well, sometimes not. When I enter the code in ghci, it works well but not when compiled. I don't know if I should explain what the code was for initially, tell me. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10688 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
