0064  * @brief Tests the ``.preinit_array`` constructor handling of the C runtime
0065  *   support.
0066  *
0067  * This test case performs the following actions:
0068  *
0069  * - Validate the ``.preinit_array`` constructor invocation.  Mark that the
0070  *   test case executed.
0071  *
0072  *   - Check that the ``.preinit_array`` constructor was called exactly once.
0073  *
0074  *   - Check that the ``.preeinit_array`` construction was done by the Classic
0075  *     API user initialization task.
0076  *
0077  *   - Check that the ``.preinit_array`` constructor was called before the
0078  *     global constructor invocations.
