Here is a summary of my experiences. I used the following:

1) boost 1.27.0
2) Borland C++ Builder command line compiler bcc32 version 5.5
3) Debug was turned on

With these 3, I was able to successfully implement a handle-body 
idiom type class. I.e. the destructor for my private body 
implementation WAS called when the handle class was destroyed. 

If instead I use auto_ptr, the destructor is NOT called.
If instead I use scoped_ptr, it will not compile due to a bug in 
Borland.

Earlier, I reported that shared_ptr didn't work but I can't reproduce 
that now. Sorry for the confusion.
