Thanks, but this looks like a completely different crash, it happened
inside GC:

The failed assertion seems to point to the latest changes which added
buffer indirection counting.  Dmitry, could you please take a look?
You can ask Christoph to look around in the crashed session, since it
is still runs under GDB.
