#13611: Segfault due to levity polymorphism of mkWeak# -------------------------------------+------------------------------------- Reporter: nomeata | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.2.1 Component: Compiler | Version: 8.1 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 simonmar): Duplicating the primop is an ugly solution to something that isn't really a problem IMO. There are lots of ways to segfault using primops! We should just document how to use them safely. If we could fix the type system to give an accurate type to this then fine, but otherwise I suggest we just improve the documentation. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13611#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
