Code for pnchisq contains following

if (tSml) {

if (x> f+ theta+ 5*sqrt(2*(f+2*theta) ))){

     return 1.; /* better than 0 --- but definately FIXME */
}

}

This needs to check which tail has been requested; it is only correct if the default lower_tail=1 has been requested; for upper tail should return 0 if more than 5 std devs away from mean under these circumstances.
