This crash (bus error) also occurs when the experiment is done the
other way around. A standard sqlite3_sequence table is then renamed
and no longer exists as such. And it will not reappear..

experiments.
$ rm test.db; sqlite3 t
I'm not working on anything specific, just experimenting, so you don't
have to rush :)

of the code where we must move cautiously to avoid a performance
regression. Further, your specific problem suggests an entire n

But it would be nice if corrupted database didn't crash the application ;)
If the database is (or appears) corrupted, terminating immediately or
"crashing" is probably the only safe
btw 'PRAGMA integrity_check;' returns 'ok'
