This might be happening because your compare function is inconsistent, e.g. when player_compare_func (foo, bar, x) returns a value < 0 and player_compare_func (bar, foo, x) returns 0 (instead of a value > 0) or player_compare_func (bar, bar, x) returns a value != 0 (instead of 0) or something similar.
