It's easily reproducable by attached python script on default build of master (SS).
nbak-test.zip

It looks like reallocated mem. And it might happen the second cache_writer for the same dbb.

The reason of a bug is ability to start more than one cache_writer thread simultaneously due to races on bcb_flags in CCH_init2.
