"It's clear to me that the phenomena (maybe not all of them, but at least
some) do occur/have occurred and anyone preserving critical software for any
length of time should take them into account; devise detection and
prophylaxis mechanisms and so on. Sort of like hardware, really."
The phenomena listed by Drew are - of course - real (even if I disagree with
the "software" label).
Dare I suggest that some on this list might like to look at some of the
features of a modern microcontroller, such as a device from the TMS570
family? These have been designed to address many of the issues that have
been raised here in the last couple of days.
