[gnugo-devel] GNUGo/kgsGtp Bug report

[Nick Wedd]

GNU go people, Bill Shubert,

I am reporting a bug in either GNU Go release 3.9, or in kgsGtp, I
cannot tell which.

On March 16th, GNU Go 3.6 (built by me from unmodified code downloaded
from the GNU Go web site) was playing, as 'gnugo3pt6', from my PC, via
kgsGtp, on KGS, against user 'skylancer'.  I have now examined the game
record, which is attached.  The sequence of events appears to be
  GNU Go plays at B9
  skylancer plays at Q6
  skylancer requests an undo, which is granted
  skylancer plays at J13
  GNU Go tries to play at B9 again, and gets booted
This is odd.  KGS users often request undoes against gnugo3pt6, and it
has not caused a problem before.

The last few lines of the kgsGtp output read
