Some classes seem to have same problem. 

  class Object
    attr_accessor :v
  end

  [ Object.new, 0, 0.0, 10**10, 1..10, Class.new, Module.new, 
    "", {}, [], //, STDOUT, Struct.new("F").new, Time.now].each do |obj|
    obj.v = "ok"
    o = obj.dup
    p [obj.type, o.v]
  end

result:

[Object, "ok"]
[Fixnum, "ok"]
[Float, "ok"]
[Bignum, "ok"]
[Range, "ok"]
[Class, "ok"]
[Module, "ok"]
[String, nil]
[Hash, nil]
[Array, nil]
[Regexp, nil]
[IO, nil]
[Struct::F, nil]
[Time, nil]
