so here we don't need a copy-constructor like in motion_data.h, MotionData(const
MotionData& other) ?

[blundell, 2016/10/24 16:25:58]

That's correct. MotionData is copied but OrientationData is not.

hmm that's weird, not sure where that would happen, i.e. what's different
between MotionData and OrientationData. any ideas?

+  ~OrientationData() {}
+
+  double alpha;
+  double beta;
+  double gamma;
+
+  bool hasAlpha : 1;
+  bool hasBeta : 1;
+  bool hasGamma : 1;
+
+  bool absolute : 1;
+
+  bool allAvailableSensorsAreActive : 1;
+};
+
+static_assert(sizeof(OrientationData) ==
+                  (3 * sizeof(double) + 1 * sizeof(char)),
+              "OrientationData has wrong size");
+
