Copy killers in the movepicker ss->killers can change while the movepicker is active. The reason ss->killers changes is related to the singular extension search in the moves loop that calls search<> recursively with ss instead of ss+1, effectively using the same stack entry for caller and callee. By making a copy of the killers, the movepicker does the right thing nevertheless.
