[gnugo-devel] regress 13x13b.17

[kevin yong]

Hi, Evan:

  i did some work on 13x13b.17:

  problem: H5 is wrong, should F1.

  i look at the log file: H1 got value 1.54, i dont
think anything wrong with that; F1 got value 0, that
is the problem.

  how F1 got value 0:

  because at examine_move_safety() stage, identify F1
as 'unsafe' move, but the result is from old chched
result;

  then i trace back to owl_reasons() stage,

    owl_does_defend A4 with F1
    Current stack: B:F1 W:B1 B:C1 
    Variation -1: DEAD 1 (cached)
  
  and the cached result dump is:
    
    Komaster 0 (0, 7) Routine 6, (-1, 15), depth:
      16 Result: 0 12, (39, 18)
