--- Comment #2 from Marc Glisse <glisse at gcc dot gnu.org> ---
Yes, this lifetime extension mechanism seems super fragile in gcc. Binding to a
base fails, binding to an array element fails
int d;
struct A
{
int i[2];
~A() { ++d; };
};
int main()
{
// int&&r = A().i[0];
const int &r = A().i[0];
if (d != 0)
__builtin_abort();
}
even a regular member fails if referenced with a slightly different syntax (bug
53288).
