Extended Description

The following code:

struct A {
using B = void (*)();
B c;
};
class D {
static const A e[];
};
class F {
public:
struct G {
unsigned h[2];
};
template I get();
};
template void j();
template <typename = void> struct K;
template <> struct K<> {
template static void m() {
F n;
auto o = n.get<F::G>();
auto [p, q] = o.h;
j();
}
};
const A D::e[]{K<>::m<0>};

makes clang to crash with:
