bug#718: Hang after window resize

[Ulrich Windl]

On HP-UX 11.31 (IA64, Itanium2) Emacs 22.2 (from HP-UX software depot)
did not respond to key presses any more after the window had been
resized vertically (made taller). I tried to send SIGINT and SIGTERM
to emacs, but nothinmg seemed to happen. Eventually it dumped core
with IOT trap. gdb says about the backtrace:

I was using PuTTY visa SSH 2 to log in, using Emacs in text mode.
Sorry, I read the notice about "backtrace full" after haing removed
the core file.

Also note that Emacs runs fine right now with the new window size.
