I could log in and out, run commands, and the $SHELL and $BASH_VERSION environment variables confirmed the change.

While logged in as my regular user, I entered chsh, but when I typed in the path, it says that I had entered an invalid shell. I tried sudo chsh, and the same. I was perplexed by this, as it seemed perfectly valid when I ran it as this user by typing the path into the command line of the previous default shell. Commands run normally, and $BASH_VERSION returns the right number. I tried to change my regular user's shell again and got the same error. I triple checked the path, and tried again, this time while logged in as root. It then returned:

At first it gave me a 'login incorrect' error, but on repeated attempts it would give what looks like a 10 or 15 line message, but the screen clears so quickly I can't read it. I logged in as root and changed my regular user's default shell back to the previous /bin/bash, and now it works fine.

from man chsh:
"The only restriction placed on the login shell is that the command name
must be listed in /etc/shells, unless the invoker is the superuser, and
then any value may be added."

So put /usr/local/bin/bash into /etc/shells

Hope, this helps.
