--- Comment #4 from Patrick Palka <ppalka at gcc dot gnu.org> ---
The capturing version of the testcase is now accepted on trunk, unfortunately
we still reject the original non-capturing version.

Another workaround that's accepted by GCC 9+ is to avoid using N in an
evaluated context in the definition of vector_type:

  using vector_type = std::array<T, decltype(N){}>;
