That is good to know that it is being addressed. I can see this current
handling of optimizations causing many of subtle non-traceable and just plain
"wonky" errors that have been see these past few days. I thought the guy who
posted it was nuts... It built and had the correct output on SuSE, but when I
tried it on Arch - WTF? they was right. Who knows in how many subtle ways that
could manifest itself. I've convinced it is as the root of the (Out of IOMMU
space) error I have in the logs, and more than likely it is responsible for my
hardlocks on the big servers. We will be looking for a fix -- hopefully soon.

Thank you for letting me know.
