Satish,
This happens on that one machine where it produces MUCH less precision then
for any other block size or machine configuration. I investigated a little when
it first happened and my guess is there some issue with the compiler producing
"bad" code on this one system.
I hate to have an alt file for a buggy compiler but don't have any other
suggestion go ahead and add the alt file.
