Subject: [ruby-core:24254] [Bug #1758] YAML fails to dump->load small specific string

Bug #1758: YAML fails to dump->load small specific string
http://redmine.ruby-lang.org/issues/show/1758

Author: abc def
Status: Open, Priority: High
Category: build
ruby -v: 1.8.7, 1.9.1

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.
