ncurrses window and keypad

In my main function I first declare a few variables and I then call
these functions:

initscr();
noecho();
cbreak();
keypad(stdscr, TRUE);
refresh();

I then draw a few horizontal and vertical lines on the "standard
screen".

Next I make a window:

new_win = newwin(5, 5, 20, 15);
box(new_win, 0, 0);
wrefresh(new_win);

Infinite loop and switch

while (1) {

ch = getch();

printw("1");

switch(ch) {

case KEY_LEFT: ....
.....

It compiles without any problems. When I execute it draws the vertical
and horizontal lines and displays the window. As soon as I press the
left arrow key I get: Segmentation fault

It never prints the 1.

you left something out, but there's not enough information to guess what.
