我在我的Qt代码上运行valgrind，即使成功退出应用程序，我也会收到valgrind的以下报告：
8,832 bytes in 92 blocks are still reachable in loss record 12 of 12<br>
at 0x4025390: operator new(unsigned int) (vg_replace_malloc.c:214)<br>

==3339== by 0x4CA5C00: QObject::connect(QObject const*, char const*, QObject const*, char const*, Qt::ConnectionType) (qobject.cpp:2599)
我断开所有信号连接并删除对象。如果我增加信号和插槽连接的数量，上述泄漏会增加。
有人可以帮忙吗？
