--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
And this one which is probably something minor but I haven't investigated:

FAIL: 30_threads/promise/requirements/lwg3466.cc (test for excess errors)
Excess errors:
/home/jwakely/build8/x86_64-pc-linux-gnu/libstdc++-v3/include/ext/aligned_buffer.h:54:
error: data member '__gnu_cxx::__aligned_membuf<int()>::_Tp2::_M_t' invalidly
declared function type


Probably due to:

#if _GLIBCXX_INLINE_VERSION
  template<typename _Tp>
    using __aligned_buffer = __aligned_membuf<_Tp>;
#else
