I believe that heap dumping is supposed to interoperate "correctly"  
with the FFI.  (You probably could not ship such heaps to other  
clients, but I think they should be fine for personal use.)

There are certainly artifacts of support for such interoperability  
floating around in the source code, and I'm pretty sure that a prior  
incarnation of the Larceny development team did experiments to confirm  
that Sparc native Larceny supported heap dumping interoperation with  
the FFI.

So I would be curious to know if you encountered bugs yourself; it  
could very well be that there are bugs for such interoperation on  
Intel native Larceny.
