EC_POINT_is_on_curve is documented to return -1 on error, 0 if it's not on the curve, and 1 if it is on the curve.
However, this breaks the standard idiom if(!EC_POINT_is_on_curve()) {
return BAD_KEY; }, because it requires an additional test for an error
condition.
I don't know what the best outcome would be in this situation.
