Использование визуального детектора утечек

У меня есть код C ++, который случайно падает. В коде я использовал некоторые библиотеки Qt. Компилятор MSVS 2010. Основываясь на некоторых предположениях о том, что это может быть связано с утечками памяти, я начал искать это с помощью Visual Leak Detector. Я очень плохо знаком с визуальным детектором утечек и обнаружением утечек памяти.

Вот код в main.cpp:

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();
return a.exec();
}

А также MainWindow Конструктор выглядит так:

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent)
,   m_Inputdevice(QAudioDeviceInfo::defaultInputDevice())
,   m_audioInput(0)
,   m_input(0)
,   m_iVolume(0)
,   m_buffer(BufferSize, 0)
,   ui(new Ui::MainWindow)
{  // LINE 23
ui->setupUi(this);
initializeAudio(); // LINE 26
udpSocket = new QUdpSocket(this);
udpSocket1 = new QUdpSocket(this);
...
char* str = new char [30];
VLDEnable();
VLDReportLeaks();
}

И деструктор это:

MainWindow::~MainWindow()
{
delete udpSocket;
delete udpSocket1;
delete m_audioInput;
delete ui;
}

Основываясь на некоторых предложениях, я просто установил его и получил следующие результаты:
