#11792: Optimised unsafe FFI call can get wrong argument -------------------------------------+------------------------------------- Reporter: Szunti | Owner: Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 7.10.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect result | Unknown/Multiple at runtime | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D2263 Wiki Page: | -------------------------------------+------------------------------------- Comment (by osa1): I added a comment to the Phab ticket. I think we should fix the code gen so that if a register is written at some point A and read at point B, it should be kept alive no matter what. It'd be great if we could write some unit tests about that, but that needs a lot of infrastructure work... -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11792#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
