Hi.

This applies to emacs-version is 18.55.4 (hp9000s300, hpux).

[deep breath...]
If I split my window vertically, and if I have truncate-partial-width-windows
set to t, and if the last displayed character before the $ on the end of
a truncated line in the left-hand window would display as quoted octal,
resulting in the last two chars displaying on the line as \$, and if I
position point beyond the quoted character's position on that line, then
the cursor will be positioned four chars beyond the \, putting it into the
next displayed buffer, even though point is still in the left-hand buffer.
[phew!]

I assume this comes about because the logic which displays the cursor
relative to an \nnn-type character doesn't take account of part of the
\nnn being hidden (I haven't looked at the source to confirm this, so it
may be bogus).  However, I just split this buffer vertically, and
edited /bin/login in the left half, and noted that, where more octal
digits were visible at the margin, the distance of the cursor into the
next buffer was consistently four chars beyond the \, putting it on the
| separating the windows in some cases.

I hope you find this useful; have a relaxing festive season.
