--- Comment #11 from Patrick Palka <ppalka at gcc dot gnu.org> ---
This is incidentally fixed for GCC 16 by r16-7491 "c++: constrained auto NTTP
vs associated constraints". Working on a more narrow fix for the release
branches...
As mentioned in one of the dups, a workaround is to replace the constrained
auto NTTP with a requires-clause:
- template <car auto c>
+ template <auto c> requires car<decltype(c)>
