--- Comment #2 from Patrick Palka <ppalka at gcc dot gnu.org> ---
A workaround is to replace the constrained auto template parameter with a
requires-clause:

-template <concepts::property auto prop, class> _column<prop> column;
+template <auto prop, class> requires concepts::property<decltype(prop)> 
_column<prop> column;
