--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:07ac550393d00fcadcee21b44abee6bb30c93949 commit r13-1390-g07ac550393d00fcadcee21b44abee6bb30c93949 Author: Jason Merrill <ja...@redhat.com> Date: Thu Jun 23 23:14:35 2022 -0400 c++: dependent generic lambda template-id [PR106024] We were wrongly looking up the generic lambda op() in a dependent scope, and then trying to look up its instantiation at substitution time, but lambdas aren't instantiated, so we crashed. The fix is to not look into dependent class scopes. But this created trouble with wrongly trying to use a template from the enclosing scope when we aren't actually looking at a template-argument-list, in template/lookup18.C, so let's avoid that. PR c++/106024 gcc/cp/ChangeLog: * parser.cc (missing_template_diag): Factor out... (cp_parser_id_expression): ...from here. (cp_parser_lookup_name): Don't look in dependent object_type. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/lambda-generic10.C: New test.
