#13227: Loss of full laziness in mapFB -------------------------------------+------------------------------------- Reporter: simonpj | Owner: nomeata Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D3067 Wiki Page: | -------------------------------------+------------------------------------- Comment (by nomeata): In fact, I tried doing that right when you posted comment:9. I tried to modify so that unwanted floating would be detectable in the output by some carefully placed `trace`, but I did not manage that. (I dislike tests that grep in `-ddump-simpl`, they are too fragile.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13227#comment:20 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
