[gnugo-devel] bug: B pass on first move

[Alain Baeckeroot]

Hello , 

I ve stepped twice on this bug :) on 9x9 h2, and 19x19 h9

at Handicap 9, with options --autolevel -M 512 --large-scale
Black pass after the first W move
Cgoban displays the first W move, the gnugo output doesn't.
All that is reproducible, and appears between 390 and 395 Mo cache. 

cgoban.gmp.BProgram: /usr/games/gnugo --mode gmp --quiet --autolevel -M 512 
--large-scale

***assertion failure:
board.c:913 - pos == PASS_MOVE || ON_BOARD1(pos) near [2321]***
