    Description

      While reading and writing continously via a QSerialPort it is leaking memory. This seems to be coming from the QWinOverlappedIoNotifier code where it seems to come via _q_notify().

      This was confirmed via the Diagnostic Tools in VS 2017 with heap profiling turned on, the leak is small but does continue to increase over time.
