 * @brief Tests the ``.preinit_array`` constructor handling of the C runtime
 *   support.
 *
 * This test case performs the following actions:
 *
 * - Validate the ``.preinit_array`` constructor invocation.  Mark that the
 *   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.
