[gnugo-devel] Bug report

[Olof Fridh]

Hi I am running a gnugo 3.5.3 bot on kgs. I have now managed to crash it 
two times in the same way (It mostly doesn't crash then I try it but with 
two similar crashes I thought I should report it).

Tried to start a 9x9 game with me as white and 0,5 komi.

Here is the error message

**assertion failure:
move_reasons.c:871 - ON_BOARD1(dr) near [110]***
