Yes, I'm still learning the basics of the code, but I'm sure the suicide
reading is wrong in this case. I have made the variable verbose=3. What I have
traced is, from the moment gnugo was "considering attack of C19", until gnugo
checked A16 in is_suicide in board.c, where I found board[41]=0 (A18 is empty).
Of course, board[41] was 1 in the early analysis stage, but I don't know yet
when it was changed to 0. Maybe somewhere it's not propagated through to the
defense checking.
The tracing message showed " A16 would be suicide".
