--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The IR definitely says it is unitialized:
  union variant_storage_impl D.73643;

  <bb 2> :
  boost::variant2::detail::variant_storage_impl<std::integral_constant<bool,
true>, boost::variant2::detail::none, boost::variant2::monostate,
int>::variant_storage_impl<1> (&D.73643, D.77838);
