The appended game crashed on NNGS with an assertion failure in the semeai code. Apparently the semeai code and the optics code disagree on whether compute_eyes_pessimistic() can return an 1122 eyevalue without providing a move. (The owl code is fine with this.) In this particular case the crash can be avoided by adding the eye pattern Pattern 6551 !.x !.x :0111 but that doesn't solve the general problem. /Gunnar (;GM[1]FF[4] SZ[19]HA[4]KM[0.5] PW[kit]WR[6k] PB[GnuGo (GNU Go 3.3.15)]BR[10k*] PC[NNGS]DT[2003-01-26]AP[gnugoclient:2.0] AB[dd][pd][dp][pp] ;W[qf];B[nc];W[nq];B[qn];W[cn];B[cl];W[fc];B[dn];W[cq];B[dq];W[cp] ;B[hq];W[do];B[cf];W[dm];B[of];W[ph];B[qj];W[kq];B[fe];W[hd];B[jc] ;W[db];B[pr];W[cc];B[ci];W[en];B[fq];W[ko];B[no];W[km];B[qe];W[cd] ;B[de];W[gp];B[cr];W[gq];B[gr];W[er];B[fr];W[br];B[dr];W[ir];B[hr] ;W[hp];B[bs];W[ar];B[fp];W[fo];B[hs];W[iq];B[rf];W[qc];B[oi];W[rd] ;B[qg];W[rb];B[hf];W[jd];B[kd];W[je];B[ic];W[he];B[gb];W[gc];B[fj] ;W[dj];B[cj];W[dk];B[di];W[ck];B[bk];W[dl];B[ml];W[bl];B[al];W[bm] ;B[hc];W[fb];B[gd];W[ge];B[fd];W[ke];B[gf];W[kc];B[ld];W[lc];B[mc] ;W[le];B[md];W[hb];B[me];W[kh];B[if];W[jg];B[gi];W[ib];B[jb];W[bj] ;B[bi];W[ak];B[nr];W[mr];B[oq];W[ns];B[or];W[mq];B[mj];W[kj];B[hk] ;W[ei];B[ej];W[hh];B[be];W[gh];B[hl];W[fh];B[jk];W[kk];B[ec];W[eb] ;B[eg];W[nn];B[mn];W[mo];B[nm];W[qm];B[np];W[mp];B[eh];W[fi];B[hj] ;W[hi];B[ab];W[rn];B[rl];W[qo];B[pn];W[po];B[on];W[qq];B[qr];W[rr] ;B[rp];W[qp];B[rq];W[ro];B[sr];W[rs];B[qs];W[re];B[sf];W[ob];B[nb] ;W[oc];B[oa];W[pa];B[na];W[pc];B[od];W[bb];B[ac];W[mh];B[oh];W[ng] ;B[ln];W[kn];B[ia];W[ga];B[mf];W[lg];B[mg];W[nh];B[li];W[lh];B[ki] ;W[ji];B[jj];W[jl]C[Program crashed. game adjourned])
