Regression: Segmentation fault with DuckDB 1.1.0 when closing connection with certain values in composite primary keys / foreign keys #85
Description
From our integration tests, this seems like a minimal reproducer. Use DuckDB 1.1.0's JDBC driver in Dbeaver, then run this script on an empty database:
CREATE TABLE a (
a INT NOT NULL,
CONSTRAINT pk_a PRIMARY KEY (a)
);
CREATE TABLE b (
b VARCHAR(400) NOT NULL,
CONSTRAINT pk_b PRIMARY KEY(b)
);
CREATE TABLE c (
b VARCHAR(400) NOT NULL,
a INTEGER NOT NULL,
x INTEGER,
CONSTRAINT pk_c PRIMARY KEY(b, a),
CONSTRAINT fk_b FOREIGN KEY (b) REFERENCES b (b),
CONSTRAINT fk_a FOREIGN KEY (a) REFERENCES a (a)
);
INSERT INTO a VALUES (1),(2),(3),(4);
INSERT INTO b VALUES ('Orell Füssli'), ('Ex Libris'), ('Buchhandlung im Volkshaus');
INSERT INTO c VALUES ('Ex Libris', 1, 1);
INSERT INTO c VALUES ('Buchhandlung im Volkshaus', 3, 1);All goes well until you disconnect (JDBC Connection.close() when doing this programmatically, or disconnect with Dbeaver or another database utility), then the JVM segfaults with this:

Here's a pure JDBC based reproducer:
try (Connection c = DriverManager.getConnection("jdbc:duckdb:segfault");
Statement s = c.createStatement()
) {
s.executeUpdate("CREATE TABLE a (a INT NOT NULL, CONSTRAINT pk_a PRIMARY KEY (a))");
s.executeUpdate("CREATE TABLE b (b VARCHAR(400) NOT NULL, CONSTRAINT pk_b PRIMARY KEY(b))");
s.executeUpdate("CREATE TABLE c (b VARCHAR(400) NOT NULL, a INTEGER NOT NULL, x INTEGER, CONSTRAINT pk_c PRIMARY KEY(b, a), CONSTRAINT fk_b FOREIGN KEY (b) REFERENCES b (b), CONSTRAINT fk_a FOREIGN KEY (a) REFERENCES a (a))");
s.executeUpdate("INSERT INTO a VALUES (1),(2),(3),(4)");
s.executeUpdate("INSERT INTO b VALUES ('Orell Füssli'), ('Ex Libris'), ('Buchhandlung im Volkshaus')");
s.executeUpdate("INSERT INTO c VALUES ('Ex Libris', 1, 1)");
s.executeUpdate("INSERT INTO c VALUES ('Buchhandlung im Volkshaus', 3, 1)");
}
