#14080: GHC panic while forcing the thunk for TyThing IsFile (regression) -------------------------------------+------------------------------------- Reporter: inaki | Owner: (none) Type: bug | Status: infoneeded Priority: high | Milestone: 8.2.2 Component: Compiler | Version: 8.2.1 Resolution: | Keywords: hs-boot Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: #13803, #13981 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by inaki): I just checked on HEAD, and the panic is not there anymore (with or without the fix to #14075). For the tip of the `8.2` branch, the panic is there with or without the fix to #14075. Interestingly, the panic when building `gi-gio` originally reported in #13803 is gone in HEAD if I include the fix to #14075 (otherwise it is still present). This is great! So I wonder if it is possible to backport to the `8.2` branch whatever fixed this in HEAD? Or alternatively, can you see any way of working around the panic reported above with `8.2`? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14080#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
