EXACTLY! - that is the only truly correct answer.

Expected/likely answers are 0 and/or 1 ... but this is NOT

Although the nasal demon theory has been around for a long time, I
am certain that this will not be the result here - not of my machines
are fitted with appropriate I/O hardware to cause this - but as was
pointed out many years ago - it COULD be the result!

Yes - this is essentually the same scenario - I just removed any
doubt caused by order of execution of function parameters - this is
an example of prime undefined behaviour.
