This bug appears not to manifest in g++-8, 9, and 10.

Of the three code samples in comment 4, the first and
third fail to compile because N is undefined. What
code was intended there? It seems like we should check
the corrected versions of those before declaring this
fixed.
The code sample in example 3 still reports failings in
g++-10.2.

--- Comment #11 from Richard Sandiford <rsandifo at gcc dot gnu.org> ---
FWIW, the following adaption of the original testcase still fails on trunk, but
is accepted by Clang:
template <int N = 4>
struct D {
using t = int __attribute__((vector_size(N * sizeof(int))));
t v;
int f1() { return this->v[N-1]; }
int f2() { return v[N-1]; }
};
int main(int ac, char**)
{
D<> d = { { ac } };
return d.f1() + d.f2();
}
Same with a typedef instead of "using". But that's probably just another
instance of PR88600/PR58855.
