Subject: [PATCH] Fix test_cpp (ensure the collector recognizes pointers to
 interiors)

* tests/test_cpp.cc (main): Call GC_set_all_interior_pointers(1)
before GC_INIT to ensure that the collector considers pointers to
object interiors as valid ones (such a pointer could emerge as
a result of a type cast to subclass in case of multiple inheritance);
add comment.
