I don't see why this should be a problem just because no current gcc
language uses precise GC. Whenever an object is instantiated, you can
just have gcc emit a quick, inline call to a GC runtime function, like:
"describe_to_gc(void* obj_addr, size_t obj_size)." The runtime GC will
also have access to class descriptions, so it can easily look at the
memory addresses stored in reference fields and build the whole
reference tree however it wants to.
