#7702: Memory Leak in CoreM (CoreWriter) -------------------------------------------+-------------------------------- Reporter: afarmer | Owner: Type: bug | Status: patch Priority: normal | Milestone: Component: Compiler | Version: 7.6.2 Resolution: | Keywords: Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: Compile-time performance bug | Difficulty: Unknown Testcase: | Blockedby: Blocking: | Related: -------------------------------------------+-------------------------------- Comment(by ezyang): In the second patch, you should either use {{{liftIO $ evaluate w3}}}, or move the seq inside the {{{return}}}, on the principle of #5129. I think both would eliminate the space leak but I'm not sure which is more semantically correct in this case. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7702#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
