I'm getting this error on https://github.com/lang/unicode_utils/blob/master/lib/unicode_utils/read_cdata.rb#L183 and

https://github.com/lang/unicode_utils/blob/master/lib/unicode_utils/read_cdata.rb#L199

I get over it when I move down the cat_buffer definition into the while block but I dont know whether this create another subtle bug.
