>Description:
The ansi termcap entry overflows a 1024 byte buffer when used with
tgetent(), tgetstr() etc...
>How-To-Repeat:
Run a program that uses tgetent() into a 1024 byte buffer & watch
the end get scribbled over (it was the stack in my case :(
>Fix:
One of:
1) Use 1200 byte buffers (Ok ok, only kidding)
2) Fix the termcap code to not overflow the buffer.
3) Switch the system to ncurses & terminfo.
