#12804: forever contains a space leak -------------------------------------+------------------------------------- Reporter: tomjaguarpaw | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: libraries/base | Version: 8.0.1 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 tomjaguarpaw): I confirm that the space leak is gone for `ReaderT` of `IO` if I define {{{#!hs f *> v = ReaderT $ \ r -> runReaderT f r *> runReaderT v r }}} I presume (but haven't checked) that the space leak is also gone for `StateT` of `IO` if the corresponding implementation for `*>` is given in the `Applicative` instance. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12804#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
