That's interesting. What kind of "problems"? Do CPU designers mess up
and leave bugs on too?  I heard of an old Intel floating point error
but nothing else. Do later versions of CPUs get these bugfixes? Or are
CPU designs pretty static until they come out with a new proc number /
proc line?

It might change my perspective on the risks of going for a "brand new" CPU.
