What steps can reproduce the bug?

run bun segfault.js and the source of bun segfault.js contains:

import { pipeline } from "@xenova/transformers";
export class SmolVector {
  store = [];
  similarityFn = (a, b) => dot(a, b) / (norm(a) * norm(b));
  constructor(extractor) {
    (async () => {
      this.extractor =
        extractor ??
        (await pipeline("feature-extraction", "Xenova/all-MiniLM-L6-v2"));
      console.log("hiiii");
    })();
  }
  async add(objects) {
    // in parallel, check if item already has an embedding, and if not, run it through extractor
    await Promise.all(
      objects.map(async (object) => {
        if (typeof object === "string") object = { chunk: object }; // reformat it
        object.id = object.id ?? randID();
        object.embedding =
          object.embedding ?? (await this.extractor(object.chunk).data);
        this.store.push(object);
      })
    );
  }
}

const myDB = new SmolVector();
await myDB.add([
  "strawberry",
  "mango",
  "pineapple",
  "duck",
  "dog",
  "horse",
  "armadillo",
]);
