 * @assertion If an exception is raised during execution of an on-catch clause,
 * this will transfer control to the handler for the finally clause, causing
 * the finally clause to execute in this case as well.
 *   If no exception was raised, the finally clause is also executed. Execution
 * of the finally clause could also raise an exception, which will cause
 * transfer of control to the next enclosing handler.
 * @description Checks that a return statement inside a finally clause aborts
 * the stack unwinding.
