QRunnable derived class Exception Triggered

[SPlatten]

I have a class derived from QObject and QRunnable:

class RDF : public QObject, QRunnable {
    Q_OBJECT:

private:
    void run();

The constructor:

RDF::RDF(const char* cpszFullPath, QObject* pParent)
            : QObject(pParent), QRunnable(),
              mblnComplete(false),
              meLastError(RDF_file_ok),
              mpdsIn(nullptr), mpobjFile(nullptr),
              mlngBScans(0), mlngLastBscans(0)
{
    if ( cpszFullPath != nullptr )
    {
        const QString cstrFullPath(cpszFullPath);
        if ( mobjReader.open(cstrFullPath) != true )
        {
            std::cerr << "Failed to open file: "
                      << cstrFullPath.toLatin1().data() << std::endl;
            return;
        }
        QThreadPool::globalInstance()->start(this);
    }
    mcnUpdate = QObject::connect(&mtmrUpdate, &QTimer::timeout,
        [this]()
        {
            if ( mblnComplete == true )
            {
                emit complete(mlngBScans);
                mtmrUpdate.stop();
                close();
                return;
            }
            if ( mlngLastBscans != mlngBScans )
            {
                mlngLastBscans = mlngBScans;
                emit bscansUpdate(mlngBScans);
            }
        }
    );
    mtmrUpdate.start(mscintUpdateInterval);
}

In the run implementation:

void RDF::run() {
    //Do something
}

When the leaves the run function an exception is triggered:

@SPlatten How does stack trace look like?

Consider this:
"QThreadPool deletes the QRunnable automatically if autoDelete() returns true (the default)" from https://doc.qt.io/qt-5/qrunnable.html

@jsulm , thank you, I will add setAutoDelete(false) to the constructor.
