How to fix the error while running ksdensity function?

I get the following error while calling the ksdensity routine. Can somebody tell me how to fix this?

The error is not reproduced in r2019a. What release are you using?

I just tried it in 2018b; again, no problems.

x = [randn(30,1); 5+randn(30,1)]; 
[f, xi] = ksdensity(x); 

Is the problem reproducible on your machine? Are you running those exact lines (above)?
