  New Revision: 58434

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=58434

  Log:
    mark created frozen strings.
    
    * hash.c (rb_hash_new_from_values_with_klass): before this fix,
      only a st table are filled with passed values. However, newly
      created frozen strings are not marked correctly only reference
      from st table. This patch marks such created frozen strings
      by Hash object which refers to the st table.
