DuckDB deno package broken & npm package segfaulting

Has anyone had any luck using DuckDB with Deno? I've tried with the npm package with segfaults on a basic test query, and with the denoland package with fails on initialization (which is especially unfortunate because it was made by one of the deno maintainers? oh well).

the one on /x should work. What’s the initialisation error?

my bad, query error not initialization but it's

error: Uncaught (in promise) TypeError: Cannot convert object to primitive value
  const view = new Deno.UnsafePointerView(BigInt(v));
                                          ^

repro:

import { open } from "https://deno.land/x/duckdb@0.1.1/mod.ts";

const db = open(":memory:");


const connection = db.connect();

connection.query('select 1');

import { open } from "https://deno.land/x/duckdb@0.1.1/mod.ts";

const db = open(":memory:");


const connection = db.connect();

connection.query('select 1');

ran w/ deno run --allow-all --unstable main.ts appears there's a PR open on the repo as well
