Short description of error
When I make a Loop Cut and make the number somewhere between 16 cuts and play fast with the smoothness it crashes.
Exact steps for others to reproduce the error
First, go to edit mode, from the UI select Loop Cut and cut the cube. Set the Number of Cuts around 16 or more and play with the Smoothness fast. It doesn't crash every time but most of the times. If it doesn't crash in the first attempt add more Loop Cuts on the other sides and again add number of cuts and play with the smoothness fast by increasing and decreasing the value
