What steps will reproduce the bug?

import { Database, constants } from 'node:sqlite';
import { constants as _constants } from 'node:buffer';
const { MAX_STRING_LENGTH } = _constants;

const db = new Database(':memory:');
// '\u20ac' is 1 UTF-16 unit but 3 UTF-8 bytes.
const name = '\u20ac'.repeat(Math.ceil(MAX_STRING_LENGTH / 3) + 10);

try {
  if (process.argv[2] === 'columns') {
    db.exec(`CREATE TABLE t (x "${name}")`);
    db.prepare('SELECT x FROM t').columns();
  } else {
    db.setAuthorizer(() => constants.SQLITE_OK);
    db.prepare(`CREATE TABLE "${name}" (x)`);
  }
} catch (err) {
  console.log(err.code);
}

Run node repro.js for the authorizer trigger and node repro.js columns for the statement.columns() trigger.

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

Always

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

Both calls should throw a catchable error and not abort the process. With a 10-character name, both complete normally. When SQLite text doesn't fit in a JS string, node:sqlite already throws ERR_STRING_TOO_LONG for column values (#66209) and for error messages. These strings should do the same.

What do you see instead?

# Fatal error
# Check failed: String::kMaxLength >= len.
