--- 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:a528594cf9a74e5a0fbac13ef673064ed73e1b89 commit r11-8033-ga528594cf9a74e5a0fbac13ef673064ed73e1b89 Author: Jason Merrill <ja...@redhat.com> Date: Wed Apr 7 14:55:48 2021 -0400 c++: using overloaded with local decl [PR92918] The problem here was that the lookup for 'impl' when parsing the template only found the using-declaration, not the member function declaration. This happened because when trying to add the member function declaration, push_class_level_binding_1 saw that the current binding was a USING_DECL and the new value is an overload, and decided to just return success. That 'return true' dates back to r69921. In https://gcc.gnu.org/pipermail/gcc-patches/2003-July/110632.html Nathan mentions that we only push dependent USING_DECLs, which is no longer the case; now that we retain more USING_DECLs, handling this case like the other overloaded function cases seems like the obvious solution. gcc/cp/ChangeLog: PR c++/92918 * name-lookup.c (push_class_level_binding_1): Do overload a new function with a previous using-declaration. gcc/testsuite/ChangeLog: PR c++/92918 * g++.dg/lookup/using66.C: New test.
