QFile::seek() to an address which is greater than 0x7FFFFFFF fails on Symbian

Steps to reproduce

1. Run the following simple app (also sis file attached)
2. Open any file on the device

   #include <QtGui>
   
   int main(int argc, char** argv)
   {
       QApplication app(argc, argv);
   
       QTextBrowser window;
       window.showMaximized();
   
       QString fileName = QFileDialog::getOpenFileName(&window, "select file", "C:/");
       if (!fileName.isEmpty()) {
           QFile file(fileName);
           if (file.open(QIODevice::ReadOnly)) {
               window.append(QString("0x7FFFFFFF: %1").arg(file.seek(0x7FFFFFFF) ? "success" : "fail"));
               window.append(QString("0x80000000: %1").arg(file.seek(0x80000000) ? "success" : "fail"));
           }
       }
       return app.exec();
   }
   

Actual result

0x7FFFFFFF: success
0x80000000: fail

Expected result

0x7FFFFFFF: success
0x80000000: success
