#13611: Segfault due to levity polymorphism of mkWeak# -------------------------------------+------------------------------------- Reporter: nomeata | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 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 goldfire): Neither do I. Though what guarantees do we provide when a user writes the `IO` constructor explicitly? This is tantamount to `unsafePerformIO`, is it not? While I conjecture that the segfault is possible without unsafe features, this test case isn't terribly convincing. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13611#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
