【QT】析构函数执行引发异常

在析构函数执行完成后引发异常，程序崩溃

造成异常的原因

在布局添加QSpacerItem 引起的异常，使用try...catch无法捕获

cpp 复制代码

 	QSpacerItem *spacer = new QSpacerItem(1, 1, QSizePolicy::Expanding, QSizePolicy::Fixed);
    QHBoxLayout *hLayout2 = new QHBoxLayout;
    hLayout2->addWidget(typeLabel);
    hLayout2->addWidget(targetTypeBox);
    hLayout2->addSpacerItem(spacer);
    hLayout2->addWidget(nameLabel);
    hLayout2->addWidget(boomNameBox);
    hLayout2->addSpacerItem(spacer);
    hLayout2->addWidget(degreeLabel);
    hLayout2->addWidget(degreeBox);
    hLayout2->addSpacerItem(spacer);
    hLayout2->addWidget(editMenuBtn[5]);
    hLayout2->addWidget(editMenuBtn[6]);

Tips

还未能搞清楚为啥添加弹簧后会出现这个异常，暂时只能在布局删掉QSpacerItem
