Thanks! ---------------------------------------- Bug #19411: GC issue with moved objects https://bugs.ruby-lang.org/issues/19411#change-106009 * Author: luke-gru (Luke Gruber) * Status: Open * Priority: Normal * ruby -v: 3.2.0 * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- This crashes: ```ruby class Obj def initialize @obj = 3 end end GC.stress = true r = Ractor.new do obj = receive p obj end obj = Obj.new r.send(obj, move: true) r.take ``` It only crashes with nested objects, if you remove the ivar set in `initialize` it works fine. Maybe missing `RB_GC_GUARD`? -- https://bugs.ruby-lang.org/
