--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note it ICEs even at -O1 with -fchecking.

Confirmed.

Simplified testcase that fails with -O1 -fchecking:
typedef int __attribute__((vector_size(16))) vec_t;

vec_t src, inv;

vec_t test(int i)
{
    vec_t y=3D{0};
    y[i] =3D (i & 1 ? inv : src)[i];
    return y;
