#8512: Add flag like '-xc' that only reports uncaught exceptions -------------------------------------+------------------------------------ Reporter: blitzcode | Owner: simonmar Type: feature request | Status: closed Priority: normal | Milestone: Component: Runtime System | Version: 7.6.3 Resolution: wontfix | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Changes (by simonmar): * status: new => closed * resolution: => wontfix Comment: The problem is that there are never any uncaught exceptions. All exceptions are caught at by something, even if it is only the outermost default exception handler that we install for all threads. Typically most exceptions will be caught and re-thrown multiple times by things like `bracket`. I agree it's noisy and undesirable, but I don't think there's anything we can do at the RTS level for `-xc`. However, there is ongoing work on stack traces which should eventually provide better facilities here. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8512#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
