Weird behavior and crash with X and TTY frame

[Dmitry Antipov]

On r112235 configured with --with-x-toolkit=gtk3 --enable-checking:

1. ./src/emacs -Q -nw
2. M-x make-frame-on-display :0.0
3. On X frame, eval: (x-popup-dialog t '("Test" ("yes" . 1)))
4. Do not touch popup, but go back to TTY frame and press C-g C-g.
5. Shell responds with:

[1]+  Stopped                 ./src/emacs -Q -nw

6. At shell prompt, resume Emacs with %1. Response is:

./src/emacs -Q -nw
Auto-save? (y or n) [answer y]
Auto-save done
Abort (and dump core)? (y or n) [answer y]

==> crash:
