Rich, it was a bug. If inserts to several tables containing an auto-inc column are wrapped inside one LOCK TABLES, InnoDB will assert in lock0lock.c, line 2843.
Workaround: remove the LOCK TABLES if you can, or LOCK just one table at a time. I have fixed the bug to 3.23.48. You will get a patch to ha_innobase.cpp if you need.
