In test_owl_attack_move (owl.c : 4942) i have in both cases  wrong dr2 
int dr2 = DRAGON2(dr).semeai_defense_target;

dr2=22  <=> B19 in _both_ cases !!!!!!
which has no link with the semeais (in near J4 or T3), and is hopefully the 
wrong color which cause the crash.

So it seems the bug is much earlier, in the definition of 
DRAGON2(dr).semeai_defense_target 

Well, thats enough for today :)
