Dr. Hipp, I believe this one may already have been fixed, and is just a similar way of triggering the underlying bug:

CREATE TABLE Table0 (Col0 DEFAULT (NOT NULL)  NOT NULL ON CONFLICT REPLACE  ) ;
CREATE TRIGGER Trigger0 INSERT ON Table0 BEGIN DELETE FROM Table0   ; END;
INSERT INTO Table0 DEFAULT VALUES ;

Fixed by check-in https://www.sqlite.org/src/info/5c7dab

I am backporting this check-in.
