Piston pushing cauldron with water or potion in it crashes the game

I was just fooling around it in survival mode when I place a sticky piston behind a cauldron with water or potion, when I activated the piston the game crashed.
Crashes happen in both survival and creative modes.

Steps to reproduce
First of all make sure you're testing this in creative.

• Place down piston.
• Place cauldron in front of piston.
• Fill cauldron with water or potion.
• Place redstone dust and add a lever to power it. (See photo attached.)
  The game WILL crash.
