Debian Bug Report for pyyaml 3.08/libyaml 0.1.2

Details can be found at:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=515634

The meat of the bug report is:

Given a small input file, such as

  - &anchor 1
  - &anchor 1

yaml.load() dies with an error:

  yaml.composer.ComposerError: found duplicate anchor 'anchor'; first occurence
    in "<string>", line 1, column 3:
      - &anchor 1
        ^
  second occurence
    in "<string>", line 2, column 3:
      - &anchor 1
        ^

This ought to be allowed; the YAML 1.1 spec says in 3.2.2.2:

  When composing a representation graph from serialized events, an alias node
  refers to the most recent node in the serialization having the specified
  anchor. Therefore, anchors need not be unique within a serialization. 


I'm not an expert in the yaml spec, so I leave it to you to decide if his 
interpretation is correct.
