[gnugo-devel] 3.1.6 to 3.1.7 breakage (VC only)

[Trevor Morris]

The following GTP script:

version
loadsgf ml.cyg/gnugo/regression/games/filllib7.sgf 72
25 gg_genmove white
top_moves_white
loadsgf ml.cyg/gnugo/regression/games/filllib8.sgf 303
27 gg_genmove white

#(version is not necessary to cause the problem)

Causes 3.1.7 built w/ VC to generate the bogus move:
=27 C19

3.1.7 built on cygwin and 3.1.6 (both versions) don't have this
problem.


An interesting line in the trace is:
... surrounded by dragon at PASS
Though, it is present in both 3.1.7 trace files.

I've attached a tar file with the log files from all four runs,
the shell script I used to launch them, and the GTP script listed
above (filename 31).
