#13424: readMutVar# is marked can_fail -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.4.1 Component: Compiler | Version: 8.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Other Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- `readMutVar#` can only fail if its argument is not a valid pointer. As far as I know, we never check whether a pointer is valid; we ensure it's valid by construction. So I think we should set `can_fail = False`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13424 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
