#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: Type of failure: Building GHC | Unknown/Multiple failed | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by dfeuer): Based on my extremely naive reading of the let/app invariant note, I'm *guessing* that the simplifier may be doing something weird like {{{#!hs ptrEq x y = let r = reallyUnsafePtrEquality# x y in isTrue# r }}} when it really should be doing {{{#!hs ptrEq x y = case reallyUnsafePtrEquality# x y of r -> isTrue# r }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13027#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
