Such as where white is in check and not on move, or white is in check by two different pieces, where there is no black move (ie a discovered check) that could have produced this position. This is caused by the indexing scheme that allows nearly all combinations of pieces on squares, whether they could actually happen or not. Nothing wrong, nothing buggy, just a fluke of the "Godel indexing scheme"...
