an code bug?

https://github.com/Musicoll/Kiwi/blob/482ac74ef71aa5159f7bf721492e8cc53b1deb4f/Client/Source/KiwiApp_Components/KiwiApp_FormComponent.cpp#L478

I do not know if it's a bug. m_alert_box.reset(new AlertBox(message, type, true, [this](){

the code above capture this variable, but the app will crash with vs2017 compiler .

when m_alert_box.reset(); is executed , the this pointer changes to an invalid pointer.
So I rewrite as

m_alert_box.reset(new AlertBox(message, type, true, [this]() {
        auto p = this;
        removeChildComponent(m_alert_box.get());
        m_alert_box.reset();
        p->setBounds(p->getBounds().withHeight(p->getHeight() - p->m_alert_height));

    }))

The point is that I save the this variable, and the app will not crash!

Maybe it's vs2017's bug .
