Tom,

To tie this with another C++ thread from a couple of weeks ago.  I guess
that I would not expect objects built with different "packing" to be
used together successfully.  ( I probably should check this with a
simple test. )  Wouldn't changing how the compiler segmented memory
for the layout of objects make vtables incompatable?
