    Maybe you need to use specbind for the `current_column' call in
    redisplay_internal instead.

    --- 10888,10894 ----
                             Fcons (make_number (redisplaying_p), 
selected_frame));
        ++redisplaying_p;
        specbind (Qinhibit_free_realized_faces, Qnil);
    +   specbind (Qinhibit_point_motion_hooks, Qt);

        {
          Lisp_Object tail, frame;

This binds the variable across nearly all of redisplay.
That is a bit drastic as a solution; it might be right,
but it is hard to be sure.

Where is the actual call to `current_column' for which you
specifically want to bind this?  Could you bind
Qinhibit_point_motion_hooks for just that?

Or what about binding it in `current_column_1'?
Maybe that is the right thing to do.
