Comment (by Mike Bibbings):

 Hi Klaas,

 My HDHomeRun Connect Quatro is new (September 2019), so power supply
 failure is not likely.

 I ran 10 channel scans using Netherlands with no seg faults and no errors
 in hdhr-dbg.log.

 One other thing I noticed in the code is that in
 HDHRStreamHandler::GetTunerStatus does not return status of the call
 hdhomerun_device_get_tuner_status(m_hdhomerun_device, nullptr, status),
 this call does have the usual result codes for Get operations i.e.
 * Returns 1 if the operation was successful.
 * Returns 0 if the operation was rejected.
 * Returns -1 if a communication error occurred.
 so HDHRSignalMonitor::UpdateValues(void) could be using invalid data.

 Mike
