>Description:
As of http://pubs.opengroup.org/onlinepubs/7908799/xcurses/standend.html standend() should turn off all attribute. A test shows that A_BOLD stays active.
>How-To-Repeat:
The following source compiled with

cc main.c -lcurses

should draw "bold" in bold and "normal" without attributes. But both are displayed in bold. If

attroff(A_BOLD);

or

attrset(A_NORMAL);

is used instead of standend() it works.

#include <curses.h>

int
main()
{
        initscr();
        attron(A_BOLD);
        addstr("bold");
        standend();
        addstr(" normal");
        refresh();
        getch();
        endwin();
        return 0;
}
