#14675: GHC 8.4.1 regression: segfault when loading doctest on a module with ANNs on Ubuntu 16.04 or later -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.4.1 Component: GHC API | Version: 8.4.1-alpha1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): Thanks, as always, for the bisection Ryan; it's incredibly helpful. I wonder if this is related to the `gold` bug that I found while writing that patch (see #13883). It seems plausible that constructor mis-ordering would result in a crash. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14675#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
