That's hard to believe.  Dr. Wrigley said the hardware failures turned
from "insideous" to "catastophic" when he changed some sort of Things to
pointers-to-Things.  I take that to mean, he got wrong answers before,
and crashes after.  Is that right, Dr. Wrigley?

Either way, the lesson should be "use reliable hardware"!
