#13027: Core lint errors compiling containers HEAD with GHC HEAD -------------------------------------+------------------------------------- Reporter: erikd | Owner: 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: Building GHC | Test Case: failed | simplCore/should_compile/T13027 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Its not about that. Lint is just blindly checking the let/app invariant. We might additionally want to check that the arguments to `reallyUnsafePtrEquality#` are indeed guaranteed evaluated... Lint could do that I suppose but it might well be a USER error not a GHC error. We don't have a good way to check for that; hence really unsafe. But I have fixed GHC's internal consistency check, which is what Lint is about -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13027#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
