[gnugo-devel] Wrong liberty counts in worms?

[Inge Wallin]

Consider the following position:

   A B C D E F G H J K L M N O P Q R S T
19 . . . . . . . . . . . . . . . . . . . 19
18 . O X X X . . . . . X . X . . . . . . 18
17 . O O X . X . O . O . O . X . . . . . 17
16 . . . O X . X O . + . . . . . X . . . 16
15 . . . O . X . X O O . . . . X . . . . 15

Now consider the worm report for some of the worms in the position:

E14 : (dragon E14) white string of size 6 (6.62), genus 0: (3,5,6,3) - is a 
cutting stone
F15 : (dragon J14) black string of size 2 (2.67), genus 0: (4,3,5,1)

The numbers in the parenthesis are the liberties, second order
liberties, and so on.  The liberties seem to be correct, but second
order and up seem to be totally bogus.

Is this just me or is something seriously wrong here?
