Problem with ncurses 5.9

[Éric LÉVÉNEZ]

Hi,

I think there is a bug in ncurses 5.9 using xterm on Ubuntu 18.04.

address@hidden:~$ ll /lib/x86_64-linux-gnu/libncurses.so.5*
lrwxrwxrwx 1 root root     17 May 23 10:08 /lib/x86_64-linux-gnu/libncurses.so.5 -> libncurses.so.5.9
-rw-r--r-- 1 root root 141248 May 23 10:08 /lib/x86_64-linux-gnu/libncurses.so.5.9

        noecho();

        mvaddstr(1, 0, "-");
        mvaddstr(2, 0, "--");

        mvaddstr(8, 0, "--------");

        mvaddstr(10, 0, "Press a key ... ");
        getch();

        clear();
        endwin();
        return EXIT_SUCCESS;
}
address@hidden:~$ echo $TERM
xterm
address@hidden:~$ ./curses_tst

Press a key ...

I get half a pine tree and not half a pyramid.
On the same PC, the same executable works fine on a VGA console (TERM=linux) or serial console (TERM=vt220).

Best regards
