=begin
YAML fails on this testcase:

require 'yaml'
YAML::load(YAML::dump("\n a\n""))

with:

/usr/lib/ruby/1.8/yaml.rb:133:in load': syntax error on line 3, col 0: "' (ArgumentError)
from /usr/lib/ruby/1.8/yaml.rb:133:in `load'
from test.rb:2

I tested this with ruby 1.8.7 and ruby 1.9.1, both failed. The testcase is very specific, change one thing and it doesn't crash anymore. I have yaml dumps with large strings and this bug was triggered 3 times.

This appears to be a duplicate of #1311, which contains a more comprehensive solution, and a patch.

Hi,

Syck is deprecated, in effect. This issue won't be fixed.
Instead, try Psych. [ruby-core:29337]
