Lagersegment fejl på debian

Hej

Jeg er igang med at lave en lille test app, hvor jeg bruger ncurses. Det jeg har lavet indtil videre, vil gerne compiles. Men jeg får en lagersegment fejl, når jeg prøver at køre den binære fil. Hvad kan der være galt

#include <menu.h>
#include <iostream>
#include <curses.h>

#define ARRAY_SIZE(a) (sizeof(a) / sizeof(a[0]))
#define CTRLD 4

using namespace std;

char *choices[] = {"Install fluxbox and ekstra tools","Configurate fluxbox","About this software",};
void print_in_middle(WINDOW *win, int starty, int startx, int width, char *string, chtype color);

int main()
{

    int c;               
    MENU *my_menu;
        WINDOW *my_menu_win;
        int n_choices, i;
   
    initscr();
    start_color();
        cbreak();
        noecho();
    keypad(stdscr, TRUE);
    init_pair(1, COLOR_RED, COLOR_BLACK);

        n_choices = ARRAY_SIZE(choices);
        my_items = (ITEM **)calloc(n_choices, sizeof(ITEM *));
        for(i = 0; i < n_choices; ++i)
                my_items[i] = new_item(choices[i], choices[i]);

    my_menu = new_menu((ITEM **)my_items);

        my_menu_win = newwin(10, 40, 4, 4);
        keypad(my_menu_win, TRUE);
   
        set_menu_win(my_menu, my_menu_win);
        set_menu_sub(my_menu, derwin(my_menu_win, 6, 38, 3, 1));

        set_menu_mark(my_menu, " * ");

        box(my_menu_win, 0, 0);
    print_in_middle(my_menu_win, 1, 0, 40, "My Menu", COLOR_PAIR(1));

    mvprintw(LINES - 2, 0, "F1 to exit");
    refresh();

                break;

                wrefresh(my_menu_win);
    }   

        unpost_menu(my_menu);
        free_menu(my_menu);
        for(i = 0; i < n_choices; ++i)
                free_item(my_items[i]);

    endwin();
    return 0;
