Erik Malund said:
a jump to zero does not reset the uC

Very true.

and is thus fraught with problems.

also true.

The only sure way to 'jump to zero' is a reset

No, a jump to zero is sure to jump to zero - there is no uncertainty about that part!

I think you mean, "the only sure way to reset the processor is with a true hardware reset"?

which can be achieved e.g. by letting a watchdog time out.

indeed.
