    c++: -Wdangling-reference not suppressed in template [PR109774]

    In check_return_expr, we suppress the -Wdangling-reference warning when
    we're sure it would be a false positive.  It wasn't working in a
    template, though, because the suppress_warning call was never reached.

            PR c++/109774

    gcc/cp/ChangeLog:

            * typeck.cc (check_return_expr): In a template, return only after
            suppressing -Wdangling-reference.

    gcc/testsuite/ChangeLog:

            * g++.dg/warn/Wdangling-reference13.C: New test.
