This looks like an incompatibility rather than a bug. As far as I
know, ruby_parser primarily supports 1.8, and I don't know how much
testing has happened against 1.9. Either way, you should probably try
to report it...somewhere :) I think ruby_parser is a great project to
have, since it allows equivalent parser support across all Ruby
implementations without any native code.
