Hi.
If 20 changed to other number 19, 21 or 20.0 , PROOT working good.
Pic. 1 - command input;
Pic.2 - after enter key pressed;
Pic.3 - result of evaluating.

Yes, in most cases the algorithm works fine, I have tested in the past up to degree 20 and worked great. However, there's no guarantee that a specific set of coefficients can be harder on the algorithm and cause problems. The good part is you provided a test case that fails 100% of the time, so I was able to reproduce it and start testing.
It will be fixed on the next update.
