segfault

How can we reproduce the crash?

ran bun create hono bun-hono and cd bun-hono then bun run dev

while the dev server is running and also navigated to the url, i modified the index.ts to the following:

import { Hono } from "hono";

const app = new Hono();

app
  .get("/", (c) => {
    return c.text("Hello Hono!");
  })
  .get("/set-cookie");

export default app;

Relevant log output
