That was only meant as an introduction. My only real point is that the particular error is not always raised. Here is a more to the point example: SQLite version 3.8.12 2015-10-07 13:24:27 Enter ".help" for usage hints. Connected to a transient in-memory database. Use ".open FILENAME" to reopen on a persistent database. sqlite> create view v as select c+1 from v; sqlite> select *from v; Error: view v is circularly defined sqlite> create view v2(c) as select c+1 from v2; sqlite> select *from v2; Segmentation fault $ Sorry for being too verbose in the original mail.
