You're right, there's no guarantee whatsoever that *any* of the code or data is 
in a valid state.

But it's much less code, so correspondingly much less likely to have been corrupted.

I prefer the "Go Directly To Jail, Do Not Pass Go, Do Not Collect $200" method 
of dealing with crashed programs, hence my preference for executing an invalid 
instruction. That comes from my experience with avionics in aircraft, where when 
an invalid state is detected the faulty box is immediately electrically isolated 
from the rest of the airplane, and the backup is engaged.

But, of course if you want logging, you'll have to risk it.

I would not enable such logging in any critical software, but it seems I am the 
only such person.
