GC issue with moved objects

Bug #19411: GC issue with moved objects

Added by luke-gru (Luke Gruber) over 3 years ago. Updated over 2 years ago.

[ruby-core:112211]

Description

This crashes:

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?
