BIND 9 crash bug #1387

We had a customer whose DNS servers (running BIND 9.2.1) crashed due
to the following bug that was fixed in 9.2.3rc1:

1387. [bug]  named could crash due to an access to invalid memory
   space (which caused an assertion failure) in
   incremental cleaning.  [RT #3588]

Obviously there's no substitute to running the latest version of BIND,
but this outage has caused a lot of carnage and they are now asking
what would trigger this crash. Obviously it mentions "incremental
cleaning" (whatever that is?) but is there a specific series of events
that would trigger a crash like this?
