          Happens when you kill yourself with an arrow of harming, while holding the totem of undying.

          Updated my comment. It is the same crash report which is already contained.

          I also noticed that having the wither II effect and under the totem of undying effect can crash the game too if the wither II kills you faster than the totem's effects run out (you MUST be holding another totem of undying for this to work).

          This one is very easy to reproduce.

          I achieved this with a potion of harming II, and holding the totem of undying in my off hand.
