#10946: Typed hole inside typed Template Haskell bracket causes panic -------------------------------------+------------------------------------- Reporter: jstolarek | Owner: (none) Type: bug | Status: new Priority: high | Milestone: 8.4.1 Component: Template Haskell | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash | Test Case: th/T10946 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by RyanGlScott): So in f64f7c36ef9395da1cc7b686aaf1b019204cd0fc, we added a test case for this that was marked as `expect_broken`. However, that program now loops infinitely on GHC HEAD! {{{ $ inplace/bin/ghc-stage2 --interactive GHCi, version 8.5.20180305: http://www.haskell.org/ghc/ :? for help Loaded GHCi configuration from /home/rgscott/.ghci λ> :set -XTemplateHaskell λ> m :: a -> a; m x = $$([||_||]) -- Loops infinitely ^CInterrupted. }}} Should we disable the test case entirely in the meantime? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10946#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
