No, it isn't the same instrument.  Your program constructs a function
call using address that has no valid instructions.  Paul's program
does nothing like that, it just attempts to write to a data address
which may or may not be in write-protected storage.  So your program
will always blow up, whereas the other one will only blow up if the
memory is write-protected.
