--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The standard does not require a diagnostic here, the error is in your code not
the library.

However, I put the following in std::atomic two days ago:

  // TODO: static_assert(is_trivially_copyable<_Tp>::value, "");

As soon as we have a working implementation of is_trivially_copyable that can
be enabled.
