Not quite, I'm afraid. Setting goal column still messes it up badly. To
reproduce:

 1. emacs -Q -f toggle-truncate-lines

 2. Don't change the size of the window. Create test buffer with
    commands:

        C-u 85 a RET
        C-u 100 b RET

 3. Move the cursor to the end of the first (the line with a's).

 4. Enable goal column: C-x C-n

 5. Repeat C-n and C-p. The column changes quite wildly.

The problem goes away if I set line-move-visual to nil.
