The following script causes a segfault in the CLI:

CREATE TABLE t1(a,b);
INSERT INTO t1 VALUES(1,2),(99,100),(4,3);
.eqp full
.stats on
SELECT * FROM t1;

This problem appears to be a case of using a prepared statement after it has been finalized. The problem was introduced by check-in [ae34edb7f4fa7b37] on 2018-03-20 and first appeared in the version 3.23.0 release.

To be clear: This is a problem with the command-line shell auxiliary program that uses SQLite. It is not a defect in SQLite itself.

This problem was discovered during internal testing and has not been reported in the wild.
