...not quite true - we're able to cause at least several SEGVs in ncurses'
tgetent() function by putting junk into terminfo files. Simply, try some
brute-force algorithms. I don't want to discuss about possible
consequences of this bug, as we haven't checked carefully terminfo format,
nor parser code.
