the vorbiscomments are not in the streaminfo.  you want to do:

FLAC::Metadata::VorbisComment tags;
if (FLAC::Metadata::get_tags("somefile.flac", tags)) {
   FLAC::Metadata::VorbisComment::Entry entry =
      tags->get_comment(tags->get_num_comments-1); //e.g. last tag
   // do something with it...
}
