Is it wrong to change QChart data from QValueAxis::rangeChanged handler?

Question

I'm trying to update data set in QChart on zooming (to avoid drawing lots of data points per pixel). For this I connect to QValueAxis::rangeChanged signal, and in the handler I remove the series and replace it with a new one.

But soon after the handler returns I get a segfault.

Here's the reduced test case:

#include <vector>
#include <QtCharts>
#include <QApplication>

class ChartView : public QWidget
{
public:
    ChartView(QWidget* parent=nullptr)
        : QWidget(parent)
        , chartView_(new QChartView)
        , axisX_(new QValueAxis)
    {
        const auto layout=new QVBoxLayout(this);
        layout->addWidget(chartView_);

        axisX_->setMinorTickCount(-1);
        connect(axisX_, &QValueAxis::rangeChanged, this, &ChartView::updateChart);
        chartView_->chart()->addAxis(axisX_, Qt::AlignBottom);

        chartView_->setRubberBand(QChartView::RectangleRubberBand);

        updateChart();
    }

private:
    void updateChart()
    {
        qDebug() << "Entering updateChart()";

        chartView_->chart()->removeAllSeries();

        const auto series=new QLineSeries;
        for (int i=0;i<10;++i)
            series->append(i, 1);

        chartView_->chart()->addSeries(series);

        {
            QSignalBlocker block(axisX_); // prevent recursive call of updateChart()
            series->attachAxis(axisX_);
        }

        qDebug() << "Leaving updateChart()";
    }

private:
    QtCharts::QChartView* chartView_;
    QtCharts::QValueAxis* axisX_=nullptr;
};

int main(int argc, char** argv)
{
    QApplication app(argc, argv);

    ChartView view;
    view.resize(800,600);
    view.show();

    return app.exec();
}

When I launch the app and simply make a rubber band selection, it immediately crashes. I've tried compiling Qt with Address Sanitizer, and here's what it gives me (full output here):

When I use Qt::QueuedConnection to connect to the QValueAxis::rangeChanged signal, the problem goes away. Apparently, at the point of emitting rangeChanged the state of the QChart and its related objects is not yet consistent, while after returning to the event loop it becomes consistent.

My question here is: is it really wrong to change QChart data from the QValueAxis::rangeChanged signal handler? Or is it simply a Qt bug, which should be reported? I can't seem to find any mentioning of this in the docs, but I don't actually have a good idea how it could be formulated.

I'm using Qt 5.12.3 and g++ 7.4.0.
