YAML bug

YAML seems to have a problem with stings over 8k in length.

require 'yaml'
x = "Z" * 8193
y x

/usr/local/lib/ruby/1.8/yaml/rubytypes.rb:315: [BUG] Segmentation fault
ruby 1.8.1 (2003-12-25) [i686-linux]

Aborted

Hmm... any ideas?

Stephen.

Thank you, updating to 1.8.2 fixes the 8k bug, but now I have another problem:

require 'yaml'
class B
  def initialize
    @a = String # any class name
  end
end
x = B.new
y x
ArgumentError: can't dump anonymous class Class

        from c:/ruby/lib/ruby/1.8/yaml/baseemitter.rb:164:in `each'
        from c:/ruby/lib/ruby/1.8/yaml/baseemitter.rb:164:in `map'

        from c:/ruby/lib/ruby/1.8/yaml.rb:218:in `y'
        from (irb):40

It would be nice if yaml could dump classname constants - Marshal does this fine.
