--- Comment #8 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Fixed for GCC 10.

For C++20 the std::atomic<T> default constructor will value-initialize its T
object, for older standards it will continue to default-initialize (which will
use a default constructor if there is one, and that's not a bug).
