It is possible to use a non-conservative GC with C++.  The requirement is
that the concept of a 'GC pointer' need to be encapsulated into a C++ class.

I have done such an implementation as part of a Master's thesis at
Cal Poly.  It worked with single inheritance only.  Unfortunately C++
multiple inheritance is incompatible even with the 'GC pointer' encapsulation
scheme.

I think the thesis can be ordered at the California Polytechnic University
library.  The thesis is called 'The "MM" Garbage Collector for C++'.
