--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Fixed for 12.1 and 11.4 by:
c++: template-id with current inst qualifier [PR102300]
The patch for PR41723 properly changed one place to look into the current
instantiation; now we need to fix this place as well.
PR c++/102300
gcc/cp/ChangeLog:
* parser.cc (cp_parser_template_name): Use dependent_scope_p.
Probably a dup of PR 41723.
