"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.
