#13055: Adding INLINABLE pragma causes GHC panic -------------------------------------+------------------------------------- Reporter: mpickering | Owner: Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 8.0.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- If you add an `INLINABLE` pragma to `<**>` in `GHC.Base` then `stage2` fails to build with an `idInfo` panic. I don't really know where to begin debugging this but it seems quite bad! Here is a build where it fails: https://phabricator.haskell.org/harbormaster/build/17389/ Here is a branch with one commit with the change: https://github.com/ghc/ghc/tree/wip/inlinable-bug -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13055 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
