[gnugo-devel] stepped on a bug, but

[yiwen chu]

loaded a game and on the next move (171), tried to list dragons.  windows 
error msg came up abnormal program termination, in the system window -
"
***assertion failure:
C:\temp\gnugo-3.2\engine\move_reasons.c:466 - k<40 near PASS***
"
seed 1059504843

however it is important to note i have been editing dragon.c so when i call 
listdragons it outputs the board to a file and a safety value of the 
current dragon.  the purpose of my code is to output the board with 0 for 
empty, 1 for black, 3 for white, 2 at origin of current black dragon or 4 
at origin of current white dragon.  i still need to adjust it so the entire 
focused dragon is of 2's or 4's depending on the selection.  then, work on 
training a neural network to recognize safety of groups.  regardless if it 
works, it is just a research project i am working on for a highschool 
summer program, but i think i could work on it afterwards as well, as it 
has become very interesting.


this is the code: starting with the original, mine marked off.
line 1190:

 gprintf("%o\n");
 for (pos = BOARDMIN; pos < BOARDMAX; pos++) {
   struct dragon_data *dd = &(dragon[pos]);
   struct dragon_data2 *d2;

   if (!IS_STONE(board[pos]))
     continue;

   d2 = &(dragon2[dd->id]);

   if (dd->origin == pos) {
