fwiw, I just tested with current ncurses on my Debian7 machine,
and it works as expected, and I compiled ncurses 5.7 to run the
same test - still works.

I'd start by checking the terminal description: if you're using anything
from Solaris itself, that's a problem.  infocmp would show where it's
read from (and interesting things like "bce" which are likely problems).

I have a to-do note dealing with "xterm+256color" on Solaris (it's
completely wrong).
