#10154: strange closure type 983040 (GHC version 7.8.3 for x86_64_unknown_linux) -------------------------------------+------------------------------------- Reporter: masterdezign | Owner: Type: bug | Status: infoneeded Priority: high | Milestone: Component: Compiler | Version: 7.8.3 Resolution: | Keywords: strange Operating System: Linux | closure type Type of failure: Runtime crash | Architecture: Blocked By: | Unknown/Multiple Related Tickets: | Test Case: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by masterdezign): Attaching the code. It is hard to determine the piece of code which fails, since it might take several hours until the problem appears. There is a clue what might be related to the problem, if you replace {{{ _ <- A.mapConcurrently calcWithMsg grid }}} in the main module (Simul.hs) with {{{ foldM calcWithMsg grid }}} then the program does not seem to fail (I am checking if that is always the case). Also, I am not sure if Data.Vector.Unboxed behaves well when using it unsafely (see Rk.hs). Thank you. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10154#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
