1. What happened
Editor crashes at selecting Clustering mode in Scene view for the project attached. Just start baking, and as soon as it gets to Clustering or Visibility stage (or later stages, or after the bake is over), select Clustering mode in Scene view. Editor crashes at this point.

2. How we can reproduce it using the example you attached
a. Open LightingTest scene
b. Start baking
c. Wait for Clustering or Visibility stage
d. Select Clustering mode in Scene view
---> Crash

This is a regression from 5.3.1p2. There, for the same scenario, this error is produced to console (lots of times, but no crash):
m_PresentShortFall >= 0
UnityEditor.DockArea:OnGUI()

Attached also system crash trace (reported by OSX, suggesting to send feedback to Apple)
