Since r254461:

70156.C:4:23: error: ‘constexpr’ needed for in-class initialization of static
data member ‘const A<0> C::a’ of non-integral type [-fpermissive]
4 | static const A<0> a = { 0 };
  |   ^
70156.C:5:20: error: ‘constexpr’ needed for in-class initialization of static
data member ‘const B C::b’ of non-integral type [-fpermissive]
5 | static const B b = { 1 };
  |^

which is also what clang++ says.  I'll add the test.

Confirmed, most likely GCC is not instainating the template here so GCC decides
it is incomplete.
