Thanks.  It is a very strange problem, with symptoms that I don't know
how to explain except by some hardware problem, or maybe some system
feature that tries to over-optimize on the machine code level.  The
only idea I have is to turn off any such "optimization" features and
run deep hardware testing software on that machine.
