+ *   test case executed.
+ *
+ *   - Check that the ``.preinit_array`` constructor was called exactly once.
+ *
+ *   - Check that the ``.preeinit_array`` construction was done by the Classic
+ *     API user initialization task.
+ *
+ *   - Check that the ``.preinit_array`` constructor was called before the
+ *     global constructor invocations.
