#13379: Space leak / quadratic behavior when inlining -------------------------------------+------------------------------------- Reporter: jberryman | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by mpickering): I think that the problem is that `>>` and then `thenIO` gets inlined which in this case causes the compiler to generate heaps of code to simplify. I tried using `Identity` and it compiled instantly. It seems plausible that that this shouldn't take a long time but more investigation into what exactly is taking a long time is needed. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13379#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
