    c++: CONSTRUCTORs are non-deduced contexts [PR104291]

            PR c++/104291

    gcc/cp/ChangeLog:

            * pt.cc (for_each_template_parm_r) <case CONSTRUCTOR>: Clear
            walk_subtrees if !include_nondeduced_p.  Simplify given that
            cp_walk_subtrees already walks TYPE_PTRMEMFUNC_FN_TYPE_RAW.

    gcc/testsuite/ChangeLog:

            * g++.dg/template/partial20.C: New test.
