I agree that it's horrible, but it's a Codeguard bug:  If you look closely
at the messages generated by codeguard you will see that the offset and
pointer address have got transposed, and if you dig further into the
assembler you should see that the codeguard helper functions are getting
called with the arguments the wrong way around!

I wish there was some way to fix this, but so far I haven't been able to
persuade Codeguard to do the right thing - it seems to be related to the
use of a union here.
