Hi, Ok, I am just learning Haskell. So, every day I open a text editor, a pdf file of a Haskell book and a terminal to run ghci. I resize the windows and go on my merry way. Yesterday I decided to install this script https://raw.githubusercontent.com/hotice/webupd8/master/session with the object to save my session windows and restore them the next day. Worked fine although I had to authorize some keyring popup box before it would work. Now I opened Google Chrome and an iHeart radio link. At this point the following appeared at the ghci prompt: Prelude> Vector smash protection is enabled. ghci continues to run fine. If I close and then re-open the iHeart link the message reappears. I am using Ububtu 16.04LTS and I don't use drugs or alcohol. Any ideas as to what is going on? Larry
