>Description:
getch(3) documents:

If the terminal is resized, getch() will return KEY_RESIZE,
regardless of the setting of keypad().

However with and without keypad(3) option, getch(3) returns -1 (ERR).

The same code works well with ncurses.
>How-To-Repeat:
#include <stdio.h>
#include <curses.h>

int
main(int argc, char **argv)
{
	initscr();
	int w = getch();
	endwin();

	printf("w=%d\n", w);

	return 0;
}

$ gcc -lcurses key.c
$ ./a.out
# resize terminal
# see report -1 (ERR)
>Fix:
N/A
