[Interest] Crash dump related to QtCharts::QDateTimeAxis destructor

[Michael R Nelson]

I'm hoping someone can give me a clue as to what this crash dump is telling me. Problem started after moving to Qt 5.9.1 snapshot, on macOS Sierra.

In my source, I have a QML ChartView with a DateTimeAxis and ValueAxis, and do series manipulation in C++.
