[YAML] quirks with \0 in double quotes

ruby-talk

Are these bugs? This is ruby-1.8.4. The YAML spec seems to say "\0" is
legit.

···

------------------------------------
require 'yaml'

m = YAML.load(<<END)
  a: 4
  b: "\0\0"
  c: 5
END

p m
puts

m = YAML.load(<<END)
  a: 4
# b: "\0\0\0\0\0\0\0\0\0\0\0\0\0"
  b: 6
  c: 5
END

p m
puts

begin
m = YAML.load(<<END)
  a: 4
  b: "\0"
  c: 5
END
rescue => ex
  p ex
  puts ex.backtrace
end

__END__

Output:

{"a"=>4, "b"=>""}

{"a"=>4}
