Correct.  The other is related to a different bug with a users
c-mode-hook that might throw an error, and how  to detect and tell them
about it.

That is probably because the old tagging information is still being
used.  If you run

M-x semantic-clear-toplevel-cache RET

in that buffer, it will flush old parsing data, or you can go into your
~/.semanticdb/ directory, and delete the cache file for emacs/src before
starting emacs, which might be better since multiple files  there could
be affected.
