#10830: maximumBy has a space leak -------------------------------------+------------------------------------- Reporter: NeilMitchell | Owner: Type: bug | Status: new Priority: normal | Milestone: 8.0.1 Component: libraries/base | Version: 7.10.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D1205 Wiki Page: | -------------------------------------+------------------------------------- Comment (by rwbarton): This is also a semantic bug because the Haskell Report specifies that `maximumBy` has the behavior of `foldl1`. We fixed this for `sum` and `maximum` and so on by making them instance methods of Foldable. We should just do the same for `maximumBy` and `minimumBy`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10830#comment:21 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
