Instead of all this "test program" non-sense, will someone
*PLEASE*  *POST*  two values that give incorrect results'
(correct and expected-buggy-values) appreciated too.

Does this ONLY occur on these two values, or is it more general?
Can someone at Intel tell us what caused the bug, and/or
more specifically how it got thru simulation without detection?

--> I'm **NOT** trying to smear anyone with this....I'd like to
know cuz we're doing LOTS of simulation here, and are constatnly
looking for pitfalls (to make improvements).
