#14789: GHCi fails to garbage collect declaration `l = length [1..10^8]` entered at prompt -------------------------------------+------------------------------------- Reporter: kabuhr | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 8.2.2 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): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): Just noticed this; quite an interesting issue. I was indeed able to reproduce this in GHC 8.4.1 and confirmed that `performMajorGC` does not cause reclaim. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14789#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
