[GHC] #16071: GHC is stuck (runs indefinitely) compiling a module

#16071: GHC is stuck (runs indefinitely) compiling a module -------------------------------------+------------------------------------- Reporter: dirtypaw | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.6.3 Keywords: | Operating System: Windows Architecture: x86_64 | Type of failure: Building GHC (amd64) | failed Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Compiling [https://github.com/agda/agda/commit/e68360b16af7865519bef77c21c66ff88139ea7e Agda] with ghc-8.6.3 using stack, ghc is stuck at [https://github.com/agda/agda/blob/master/src/full/Agda/Syntax/Internal.hs this module] (runs for 20+ min with no progress). It looks like a regression in ghc-8.6.3 on Windows as Agda is successfully built with ghc-8.6.2 on the same machine, and Agda build with ghc-8.6.3 is generally supported (see [https://github.com/agda/agda/issues/3442 this issue]). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16071 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Given that that module uses Template Haskell splices, this is a duplicate of #16057, so I'll close this ticket in favor of that one. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16071#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Is this ticket Windows-specific too? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16071#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
