--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 47082 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=47082&action=edit gcc10-pr90947.patch Here is an untested patch that fixes it for -std=c++17/-std=c++2a, though not for C++11/14, next_initialized_field (TYPE_FIELDS (type)) for std::atomic<int> is NULL in those cases, as that class contains no non-static data members directly, just has __atomic_base as a base class. The initializer has init list type in both cases, dunno if we don't need to treat those specially or how else to fix C++11/14.
