[gnugo-devel] final_score bug

[Darren Cook]

Running final_score caused the below problem [1]. I'd had the connection
open and been asking gnugo to evaluate positions for nearly 3 hours, so
maybe there was some build-up of bad state? When I restarted the script
it happily continued past this position.

And now it fails a few minutes later on [2]. (And again, once restarted
it happily scored it.)
