I use GnuGo 3.5.6 via Goban 6.5.1 (MacOS 10.2.8), but i get a crash very often.
Here is the last one (see below GnuGo.crash.log): I played white with 3 handicap stones for Gnugo on a 9 x 9 board.
It crash always at the same move (see the sgf file).
Exception: EXC_BAD_ACCESS (0x0001)
Codes: KERN_INVALID_ADDRESS (0x0001) at 0xbff7fdb0
