[gnugo-devel] GNU Go 3.5.7 and latest CVS crash in KGS game

[Tom Schumm]

My robot (GnuGoCVS) blew chunks on move 127 of the attached game.  The 
following will cause an assertion failure with 3.5.7 and the latest CVS:

# gnugo -l 2004-06-03-R-no-GnuGoCVS.sgf -L 127

***assertion failure:

[ ...several more printouts of the board followed... ]

I was not able to reproduce the problem with 3.5.6, so it appears to be a 
regression some time after that.
