Repro without std::vector:

template <class V>
void urgh()
{
    const V x[] =3D {V(0), V(1), V(2), V(0)};

    [&]() {
        for (auto& v : x) {}
    }();
}

void no_urgh()
{
    using V =3D int;

    const V x[] =3D {V(0), V(1), V(2), V(0)};

    [&]() {
        for (auto& v : x) {}
    }();
}

int main()
{
    no_urgh();
    urgh<int>();
}=
