--- Comment #3 from Martin Uecker <muecker at gwdg dot de> ---
Was just to file this bug...=20=20

Note that the access attribute could be translated into the same builtin
suggested for counted_by in

https://gcc.gnu.org/pipermail/gcc-patches/2023-October/634177.html

and then this could work.  This would also simply the BDOS path I think bec=
ause
special code for the access attribute could go.

Example: https://godbolt.org/z/1TTePn7hn=20

static
#if 0
char *propagate(char *p, int s)
    [[gnu::access(read_only, 1, 2)]]
#else
char *propagate(char *p; int s;=20
    char p[(p =3D pointer_with_size(p, s), s)], int s)
#endif
{
    printf("%ld\n", __builtin_dynamic_object_size(p, 0));
    return p;
