--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:3a17a1842350e7a9a6e81931e8ad66184b33efb2 commit r11-9825-g3a17a1842350e7a9a6e81931e8ad66184b33efb2 Author: Jason Merrill <ja...@redhat.com> Date: Sat Mar 26 22:05:53 2022 -0400 c++: CTAD and member function references [PR103943] More quirks of rewriting member references to dependent references for CTAD. A reference to a member of dependent scope is definitely dependent. And since r11-7044, tsubst_baselink builds a SCOPE_REF, so tsubst_qualified_id should just use it. PR c++/103943 gcc/cp/ChangeLog: * pt.c (tsubst_qualified_id): Handle getting SCOPE_REF from tsubst_baselink. (instantiation_dependent_scope_ref_p): Check dependent_scope_p. gcc/testsuite/ChangeLog: * g++.dg/cpp1z/class-deduction109.C: New test.
