Bug #19411
openGC issue with moved objects
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
?

The issue is again with shapes (related to https://bugs.ruby-lang.org/issues/19409). Newly moved objects (class MovedObject) need to have their shape reset to root shape. I'll make a PR for this.
