--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This has been the intentional behavior before when -fsanitize-recover=address
has not been supported.  Now it is just a backwards compatibility thing, unless
clang went away and redefined -fsanitize=recover=all to mean also address
sanitization, in that case we could consider changing this.
