#4012: Compilation results are not deterministic -------------------------------------+------------------------------------- Reporter: kili | Owner: Type: bug | Status: new Priority: high | Milestone: 7.12.1 Component: Compiler | Version: 6.12.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Other | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by puffnfresh): I'm going to try and start submitting data when I hit this bug. Here is a diff of the Data.ByteString.Interal interface which I had built locally vs the one in Nix's cached GHC: https://gist.github.com/puffnfresh/fe3c86baf416114ef644#file-local-vs- cached-diff There seems to be some slightly different strictness and unfolding. The full files are included in that gist, in case they help. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/4012#comment:91 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
