 From normal IRB

 >> class StringChild < String; end
 => nil
 >> c = StringChild.new
 => ""
 >> c.class
 => StringChild
 >> d = c.dup
 => ""
 >> d.class
 => StringChild


 from macirb (0.5b1)

 >> class StringChild < String; end
 => nil
 >> c = StringChild.new
 => ""
 >> c.class
 => StringChild
 >> d = c.dup
 => ""
 >> d.class
 => NSMutableString


 I found this through trying to use the BlueCloth gem (renders Markdown to
 HTML).
