The sqlite_rename_parent() SQL function is an undocumented function used as part of the implementation of ALTER TABLE. This function should never be access by an application. But if an application does invoke the function and gives it a NULL parameter in the 1st or 2nd argument, a crash might result.
The problem appears to have existed since ALTER TABLE was first enhanced to be able to deal with foreign key constraints, by check-in [b4a10c39e726dc190] on 2009-09-26 for SQLite version 3.6.19.
