Well, boehm-gc isn't a moving collector, but it is possible you have
objects that are swept prematurely.
If a C++ object contains references to Java objects, they won't be seen by
the collector.

I don't know. You could try to override the "new" operator to place C++
objects where they will be traced. But that exposes details of the
collector implementation, and could have other pitfalls when done
together with libgcj. See boehm-gc/include/gc_cpp.h for more info.
