#14970: GHC.Err.errorWithoutStackTrace produces stack trace when profiling enabled -------------------------------------+------------------------------------- Reporter: rotaerk | Owner: simonmar Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: libraries/base | Version: 8.2.2 Resolution: | Keywords: Operating System: Linux | Architecture: Type of failure: Incorrect result | Unknown/Multiple at runtime | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D4648 Wiki Page: | -------------------------------------+------------------------------------- Changes (by dfeuer): * cc: dfeuer (added) Comment: bgamari, that's a bit tricky. It's only possible to avoid building the call stack if the demand analyzer can see that it won't be used. I think the only reliable way to avoid building one is to be careful with your constraints. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14970#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
