I've been using gnugo to help improve my go skills, and I find it very
helpful. Thank you for making this available. I decided to try development
version 3.7.2, and found a problem with:
gnugo --score estimate -l anygame.sgf
This gives me a segmentation fault. I tried the latest CVS version and got
the same thing. Not that it matters, but this is on a relatively unmodified
SuSE 9.1 Linux system, with gnugo compiled with gcc 3.3.3.
So I tracked the problem down, and found that sometimes gnugo_estimate_score
is called with NULL arguments, but the function doesn't test for that.
Here's a trivial patch which fixes the problem:
