#10176: Invalid core generated with GHC 7.10 RC3 -------------------------------------+------------------------------------- Reporter: NeilMitchell | Owner: Type: bug | Status: new Priority: high | Milestone: 7.10.1 Component: Compiler | Version: 7.10.1-rc3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by nomeata): Or not quite. I think I did find a bug, but not the only one: With the change in Phab:D747, my small example and your example, when merged into one module, no longer fail. But your original test case still fails with Call Arity, and compiles fine without. There still seems to be some fishiness with Call Arity and `undefined`. /me continues brooding over the Core. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10176#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
