--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Patrick Palka <ppa...@gcc.gnu.org>: https://gcc.gnu.org/g:660cbbae327fbfa315e26d286b03efffc3c21cb5 commit r11-8730-g660cbbae327fbfa315e26d286b03efffc3c21cb5 Author: Patrick Palka <ppa...@redhat.com> Date: Thu Jun 24 13:11:44 2021 -0400 c++: alias CTAD and aggregate deduction cand [PR98832] During alias CTAD, we're accidentally ignoring the aggregate deduction candidate for the underlying template because this guide is added separately via maybe_aggr_guide (which doesn't yet handle alias templates) instead of via deduction_guides_for (which does). This patch makes maybe_aggr_guide handle alias templates in a manner similar to deduction_guides_for. PR c++/98832 gcc/cp/ChangeLog: * pt.c (maybe_aggr_guide): Handle alias templates appropriately. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/class-deduction-alias9.C: New test. (cherry picked from commit c761be53f6b62e22ac5de18c4aaf88648f64f5b7)
