RadioButton is leaking when loaded and unloaded

Odder

Hi,
I have encountered a problem with the QML Loader element and the QML RadioButton element. When I load and unload a QML Component that contains a RadioButton element I observe memory leaks.

I have made a small example:

main.cpp:

#include <QGuiApplication>
#include <QQmlApplicationEngine>

int main(int argc, char *argv[])
{
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    engine.load(QUrl(QLatin1String("qrc:/main.qml")));

    return app.exec();
}

main.qml:

import QtQuick 2.1
import QtQuick.Controls 1.0
import QtQuick.Layouts 1.0

ApplicationWindow {
    visible: true
    width: 640
    height: 480
    title: qsTr("Loader memory leak test")

    Loader {
        id: loader
        anchors {
            horizontalCenter: parent.horizontalCenter
            verticalCenter: parent.verticalCenter
        }
    }

    Row {
        anchors {
            bottom: parent.bottom
            horizontalCenter: parent.horizontalCenter
            margins: 10
        }
        spacing: 10

        Button {
            text: "Component 1"

            onClicked: {
                loader.source = "Page1.qml"
                gc()
            }
        }

        Button {
            text: "Component 2"

            onClicked: {
                loader.source = "Page2.qml"
                gc()
            }
        }
    }
}

Page1.qml:

import QtQuick 2.1
import QtQuick.Controls 1.2

Item {

    Repeater {
        model: 1000
        anchors.fill: parent

        RadioButton {
            text: "Component 1"
        }
    }
}

Page2.qml:

import QtQuick 2.1
import QtQuick.Controls 1.2

Item {

    Repeater {
        model: 1000
        anchors.fill: parent

        RadioButton {
            text: "Component 2"
        }
    }
}

Has anyone else experienced this issue? If that is the case, how did you solve it?
