Your patch fixes this crash, however it introduces a new crash when
opening a new frame in emacs -nw. This crash is not present without your
patch.
In addition, I've also found another related issue that was present
before your patch, though it might be better suited for bug #18136.
After opening emacs -nw and resizing the terminal or creating a new
frame [C-x 5 2], the modeline moves down a line and overlaps the
echo area. It is then possible to get the modeline back up by either
closing all subsequent frames [C-x 5 0] or turning the menu bar off
and on [M-: (menu-bar-mode -1) RET M-: (menu-bar-mode 1) RET]
As for the crash:
Steps to reproduce (with your patch applied):
1. emacs -Q -nw
2. C-x 5 2
