--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The first testcase produces:
<source>:41:8: error: 'ProducerAccess' is not a template
   41 | struct ProducerAccess {
      |        ^~~~~~~~~~~~~~
<source>:14:16: note: previous declaration here
   14 |   friend class ProducerAccess;
      |                ^~~~~~~~~~~~~~


Which is exactly what you expect.
