#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 RyanGlScott): Sorry, it turns out I was using `fpco/stack-build`, not `snoyberg/stackage:nightly`. I don't have the time to dig into this mess right now, but out of curiosity, can I be assured that I will have the same build environment on the `snoyberg/stackage:nightly` Docker image in the future? The use of the tag `nightly` scares me—is there a way to use the digest SHA to ensure that I can achieve the same environment later? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12168#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
