The single character difference tends to corroborate the cause of the bug:
the reference that's generated by #to_yaml fails if it comes earlier in the
map - first, not last, not sure the details.

As to where to post bugs, Syck has been accepted into the standard library
(one of many incredible contributions by _why) so I'd imagine that the bugs
would be posted to http://redmine.ruby-lang.org/
