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  
&nbsp;&nbsp;def initialize  
&nbsp;&nbsp;&nbsp;&nbsp;@a = String # any class name  
&nbsp;&nbsp;end  
end  
x = B.new  
y x  
ArgumentError: can't dump anonymous class Class  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;from c:/ruby/lib/ruby/1.8/yaml/rubytypes.rb:9:in `to\_yaml'  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;from c:/ruby/lib/ruby/1.8/yaml/baseemitter.rb:175:in `map'  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;from c:/ruby/lib/ruby/1.8/yaml/baseemitter.rb:164:in `each'

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;from (irb):40

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