    c++: ICE with using and enum [PR100659]

    Here the code for 'using enum' is confused by the combination of a
    using-decl and an enum that are not from 'using enum'; this CONST_DECL is
    from the normal unscoped enum scoping.

            PR c++/100659

    gcc/cp/ChangeLog:

            * cp-tree.h (CONST_DECL_USING_P): Check for null TREE_TYPE.

    gcc/testsuite/ChangeLog:

            * g++.dg/parse/access13.C: New test.
