--- Comment #14 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:0f50f6daa140186a048cbf33f54f4591eabf5f12 commit r11-291-g0f50f6daa140186a048cbf33f54f4591eabf5f12 Author: Jason Merrill <ja...@redhat.com> Date: Mon May 11 15:46:59 2020 -0400 c++: tree walk into TYPENAME_TYPE. While looking at 92583/92654 it occurred to me that typename types needed the same fix. So extract_locals_r also needs to see the TYPE_CONTEXT of a TYPENAME_TYPE. But it must not look through a typedef. Most tree walking in the front end wants to walk through the syntactic form of a type of expression, and doesn't care about the type referred to by a typedef. But min_vis_r does care. gcc/cp/ChangeLog 2020-05-11 Jason Merrill <ja...@redhat.com> PR c++/92583 PR c++/92654 * tree.c (cp_walk_subtrees): Stop at typedefs. Handle TYPENAME_TYPE here. * pt.c (find_parameter_packs_r): Not here. (for_each_template_parm_r): Clear *walk_subtrees. * decl2.c (min_vis_r): Look through typedefs.
