#10535: Float out causes major space leak -------------------------------------+------------------------------------- Reporter: AlexET | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by AlexET): {{{-fno-state-hack}}} makes no difference {{{-fno-full-laziness}}} does fix the problem. In many ways the float out pass is doing what it is supposed to (floating out a shared value though a lambda) as it now does less work. However the list which is floated out is produced and consumed lazily and hence the floating out causes a major space leak (space leak may be the wrong term as the extra is constant but very large (1GB)). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10535#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
