--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Fixed by r15-3532:

  c++: exception spec and stdlib specialization
  We were silently accepting the pr65923.C specialization of std::swap with
  the wrong exception specification; it should be declared noexcept.  Let's
  limit ignoring mismatch with system headers to extern "C" functions so we
  get a diagnostic for the C++ library.
