GCC defines the members as deleted, so you don't get an error unless you try to
use them. That seems to be correct according to [dcl.fct.def.default] p2 which
has a very similar example:
~S() noexcept(false) = default;
// deleted: exception specification does not match
I think Clang might implement the suggested direction for
https://wg21.link/cwg1854 but GCC is correct according to the current standard.

4.9.0 accepts it, but 4.8.x rejects it.
