  New Revision: 67483

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=67483

  Log:
    Add error globals to mark list so they don't move
    
    JSON gem is referencing constants defined in Ruby then keeping a
    reference as a global.  We need to register these globals so they stay
    pinned.
