Multiple Undo/Redo Causing Premiere to Freeze/Crash (CC 2017.0.1)

On a number of separate occasions, with different projects, I have experienced an issue in which multiple and often rapidly successive Undo or Redo actions are causing Premiere Pro to freeze (spinning beachball) and ultimately crash or require a Force Quit. I always use the keyboard shortcuts Cmd+Z or Cmd+Shift+Z and am running CC 2017.0.1 on Mac OS Sierra (10.12.2). Anyone else experiencing these problems? Probably just a bug that needs to be squashed?

(My business partner always makes fun of me for how many shortcuts I know, joking that I enter them faster than the computer can think and that's what causes apps to crash on me so often… He may actually be onto something this time!)
