#12096: Attach stacktrace information to SomeException -------------------------------------+------------------------------------- Reporter: ndtimofeev | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Core Libraries | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by mnislaih): Sounds like you are comparing the costs of 1) adding CallStacks to individual exception types vs 2) fixing call-rethrow occurrences to use the `...WithCallStack` variants. And concluding that the cost of 2) is higher, therefore `SomeExceptionWithCallStack` is a more expensive solution. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12096#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
