This patch fixes this. It turns out we don't maintain the relevant visibility flags for alias templates (e.g. TREE_PUBLIC is never set), so continue to ignore alias template template arguments for now. PR c++/70413 PR c++/107906 gcc/cp/ChangeLog: * decl2.cc (min_vis_expr_r): Handle PTRMEM_CST and TEMPLATE_DECL other than those for alias templates. gcc/testsuite/ChangeLog: * g++.dg/template/linkage2.C: New test. * g++.dg/template/linkage3.C: New test. * g++.dg/template/linkage4.C: New test. * g++.dg/template/linkage4a.C: New test.
