Subject: proc arg to Marshal.dump in 1.6.7


The proc arg to dump is broken in 1.6.7:

  str = Marshal.dump [1,2,3]
      # ==> "\004\006[\010i\006i\ai\010"
  Marshal.load str, proc {|x|}
      # ==>  NameError: undefined method `yield' for #<Proc:0x40214384>
                     from (irb):2:in `load'
                     from (irb):2

I fixed this by replacing the "yield" in marshal.c with "call". I guess
Proc#yield was imported from future?
