* array.c (rb_ary_times): Array#* should return an instance of

  the class of right operand.  [ruby-dev:24526]

* ext/zlib/zlib.c (zstream_detach_buffer): should not expose
  class-less object to Ruby world. [ruby-dev:24530]

* eval.c (proc_dup): provide Proc#dup as well.  [ruby-talk:116915]

* eval.c (ruby_exec): stack marking position may be higher than
  expected.  thanks to Guy Decoux.  [ruby-core:03527]
