Dear all

I'd like to ask you question about memory leak in Webkit. Currently, I am using
QtWebkit self contained in Qt 4.8.0, and my test application is like follows:

int main(int argc, char *argv[])
    QApplication a(argc, argv);
    QWebView* view = new QWebView();
    delete view;
    return 0;

As you know, Webkit provide RefCountedLeakCounter class to detect memory leak. When I run this test application in debug mode, I have noticed that many WebCoreNodes and CachedResource have leaked. This leak could be a big problem because we want to make use of WebKit in embedded device.

So, I'd like to ask you all whether this memory leak real or not? I just can't believe Webkit would leak memory in such a simple test, or if Webkit provides some other mechanism to ensure memory will not be leaked, please tell me.

Can anyone provide some information about this problem? I really appreciate your help.

Best Regards
Eric Chen
