Here is a simplified version of the file which gets the crash:

(;GM[1]FF[3]
RU[Japanese]SZ[9]HA[0]KM[5.5]
PW[White]
PB[Black]
GN[White (W) vs. Black (B)]
DT[2002-10-24]
SY[Cgoban 1.9.13]TM[30:00(5x1:00)];B[fd];W[eb];B[fb]
;W[ec];B[fc];W[ed];B[gd];W[ff];B[hd];W[ge];B[ca];W[hb];B[cb]
;W[ba];B[cc];W[bb];B[cd];W[bc];B[bd];W[cg];B[be];W[bg];B[bf]
;W[ag];B[af];W[dg];B[ac];W[eg];B[de];W[fg];B[tt];W[gg];B[tt]
;W[hg];B[tt];W[ig];AW[ce][de]
)

You can see that at the end you try to add a W stone at
de=D5 (AW[ce][de]) but there is already a black stone there.

GNU Go should reject the sgf file but not crash with
an assertion.
