    c++: ICE with loopy var tmpl auto deduction [PR109300]

    Now that we resolve non-dependent variable template-ids ahead of time,
    cp_finish_decl needs to handle a new invalid situation: we can end up
    trying to instantiate a variable template with deduced type before we
    fully parsed its initializer.

            PR c++/109300

    gcc/cp/ChangeLog:

            * decl.cc (cp_finish_decl): Diagnose ordinary auto deduction
            with no initializer, instead of asserting.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp1y/var-templ79.C: New test.=
