--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Yes, it is documented.
The comment needs to be followed after optional whitespace and other comments
by @code{case} or @code{default} keywords or by a user label that precedes some
@code{case} or @code{default} label.
So the reporter has just not read the documentation.
They can either move the comment, or use attribute which can be used even
inside of the {}s.
