    * vm.c (rb_thread_mark): mark a working Proc of bmethod
      (a method defined by define_method) even if the method was removed.
      We could not trace working Proc object which represents the body
      of bmethod if the method was removed (alias/undef/overridden).
      Simply, it was mark miss.
      This patch by Kazuki Tsujimoto. [Bug #7825]
      NOTE: We can brush up this marking because we do not need to mark
      `me' on each living control frame. We need to mark `me's
      only if `me' was free'ed. This is future work after Ruby 2.0.0.

    * test/ruby/test_method.rb: add a test.
