About QLocalSocket problem

[wojiaoguowei]

Below is my test code.I found clent applition memory leak.If I use QTcpSocket,the memory is normal.Is the problem the QT bug?

QLocalSocket ls;
ls.connectToServer("test");

int i = 0;

while (ls.waitForConnected())
{
QString message = QString::number(i) + "TTTTTTTTTT";

ls.write( message.toStdString().c_str(), message.length());

ls.flush();

ls.waitForBytesWritten();

Sleep(20);

i++;
}
