[gnugo-devel] Uninitialized conditional jump

Running GNU Go 3.6 pre2 with Valgrind reported the
following during strategy.tst:

==14509== Conditional jump or move depends on uninitialised value(s)
==14509==    at 0x80D2879: break_in_goal_from_str (breakin.c:290)
==14509==    by 0x80D2C03: break_in_goal (breakin.c:374)
==14509==    by 0x80D2E01: break_territories (breakin.c:425)
==14509==    by 0x80C9967: estimate_territorial_value (value_moves.c:2294)

(14509 is just the process number.)

Since Valgrind complained at line 290 but not at the earlier
line 285, I infer that goal[pos] is initialized but
goal[pos+delta[j]] is not. So this must be some problem
at the edge of the board.
