    c++: Do not warn about lifetime of std::initializer_list<T>& [PR102482]

    An initializer-list constructor taking a non-const lvalue cannot be
    called with a temporary, so the array's lifetime probably doesn't end
    with the full expression. -Winit-list-lifetime should not warn for that
    case.

            PR c++/102482

    gcc/cp/ChangeLog:

            * init.c (maybe_warn_list_ctor): Do not warn for a reference to
            a non-const std::initializer_list.

    gcc/testsuite/ChangeLog:

            * g++.dg/warn/Winit-list5.C: New test.
