#13886: GHC panic when using GHC plugins -------------------------------------+------------------------------------- Reporter: Darwin226 | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.2 Keywords: | Operating System: Windows Architecture: x86_64 | Type of failure: Compile-time (amd64) | crash or panic Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- I'm running GHC 8.0.2 on Windows 10. At first I was playing around with making my own type-checker plugin and I kept getting {{{#!hs ghc.EXE: panic! (the 'impossible' happened) (GHC version 8.0.2 for x86_64-unknown-mingw32): Static flags have not been initialised! Please call GHC.parseStaticFlags early enough. }}} on certain function calls (things like printing Docs). But now on an unrelated project I tried using the dump-core plugin and I'm getting the same error. The minimal example I can produce is simply {{{#!hs module Main where main = return () }}} compiled with `stack exec ghc -- -fplugin=DumpCore PluginTest.hs` (or I'm guessing equivalently `ghc -fplugin=DumpCore PluginTest.hs`) Make sure to install the dump-core package first. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13886 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
