fwiw, this was confirmed to me on IRC in #tmux.

The size of my screen (read : the size of my gnome-terminal frame) can
be different when I detach and when I reattach (because I sometimes
maximize the frame, some other times not -- also because I use screen of
different sizes.)

On my laptop, over ssh:
- when I don't maximize my gnome-terminal frame, then gdb reports:
  FrameRows(current_tty) = 23.
- If the gnome-terminal frame is maximized, gdb reports 42.

(In case you wonder, I tried detaching when not-maximized, then
maximizing gnome-terminal and then reattaching : it worked fine.)
