#12168: panic! (the 'impossible' happened) with gi-gtk 3.0.4 -------------------------------------+------------------------------------- Reporter: drb226 | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by inaki): (Maintainer of `haskell-gi` here.) The bindings are indeed autogenerated. To generate a package that includes the code giving rise to the panic, run (in the machine/docker image where you get the panic) {{{ $ wget https://hackage.haskell.org/package/gi-gtk-3.0.4/gi- gtk-3.0.4.tar.gz $ tar xvzf gi-gtk-3.0.4.tar.gz $ cd gi-gtk-3.0.4 $ cabal configure $ cabal clean $ cd .. $ tar -czf gi-gtk-3.0.4.tar.gz gi-gtk-3.0.4 }}} This will generate a tarball of the package including the autogenerated code, which you can upload somewhere for examination. Note that further `cabal configure`s will not rewrite the autogenerated code (located in the `GI` directory). (Also, for what it is worth: I cannot reproduce the panic on my computer either.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12168#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
