sqlite: Session methods crash after DatabaseSync is closed and reopened #64782

Version

main

Platform

macOS 26.5.2

Subsystem

sqlite

What steps will reproduce the bug?

import { DatabaseSync } from 'node:sqlite';

const method = process.argv[2] ?? 'changeset';
const db = new DatabaseSync(':memory:');

db.exec('CREATE TABLE data (id INTEGER PRIMARY KEY)');
const session = db.createSession();

db.close();
db.open();

console.log(`calling session.${method}()`);
session[method]();
console.log('returned');

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior? Why is that the expected behavior?

Closing the database should invalidate associated session wrappers; after reopening, either method should throw an error such as Error: session is not open.

What do you see instead?

$ ../node/node repro.js changeset
calling session.changeset()
[1]    65858 segmentation fault  ../node/node repro.js changeset

$ ../node/node repro.js close
calling session.close()
[1]    66266 segmentation fault  ../node/node repro.js close

Both methods terminate the process because the session wrapper retains a stale native handle after db.close().
