关于串口接收时运行错误

QByteArray temp = myCom->readAll();
            QString str(temp);
            QStringList list1=str.split(" ",QString::SkipEmptyParts);               
            QString a=list1[0];
            QString b=list1[1];
            QString c=list1[2];
            QString d=list1[9];
            ui->tableWidget->setItem(0,0,new QTableWidgetItem(a));
            ui->tableWidget->setItem(0,1,new QTableWidgetItem(b));
            ui->tableWidget->setItem(0,2,new QTableWidgetItem(c));
            ui->tableWidget->setItem(0,3,new QTableWidgetItem(d));

一运行接收数据时就显示错误

------解决方案--------------------
QStringList list1,你怎listl的个数，

int cnt = list1.count();
if (cnt > 9)
{
QString a=list1[0];
            QString b=list1[1];
            QString c=list1[2];
            QString d=list1[9];
}
