I spent a long time today stepping through the debugger and looking at
the address locations of the record elements in both Ada and the
corresponding C Structure.

It looks like the rep spec that GNAT generated was not aligning some
of the values the way it wanted to. I was able to manually adjust the
rep spec (and the C struct) - and now GNAT is happy with the results.

Not sure why GNAT didn't align the items properly to begin with...
