bun crashed "Segmentation fault"

[scffs]

How can we reproduce the crash?

I wrote a simple code that only make requests to server in a while. It is possible that the crash is in PC lock mode (Control-Command-Q)

Relevant log output

oh no: Bun has crashed. This indicates a bug in Bun, not your code.

Any chance you could provide some code for us to reproduce the issue? The crash is saying that it is something to do with the HTTP client. But it's hard to assess further than that.

yes sure

import { connect } from 'mongoose'

const delay = (ms) => new Promise((resolve) => setTimeout(resolve, ms))

const connectToDatabase = async () => {
  try {
    await connect('mongodb://localhost:27017/test')
  } catch (error) {
    process.exit(1)
  }
}

export const getSmth = async () =>
  fetcher('https://jsonplaceholder.typicode.com/posts')

const fetcher = async (url, body = '{}') => {
  let items

  const response = await fetch(url, {
    method: 'POST',
    headers: {
      Authorization: '123',
      'Content-Type': 'application/json'
    },
    body
  }).catch((error) => {
    console.error(`Error (${new Date().toISOString()}): ${error}`)
  })

  try {
    const r = await response.json()

    // IDK why there is no return but it works
    if (response.status !== 200) {
      console.error(r)
    }

    console.log('r', r)

    items = r
  } catch (err) {
    return null
  }

  await delay(450)
  return items
}

// a simplified version of my code
async function main() {
  // could comment this I guess
  await connectToDatabase()

  // I'm getting some data to display it in the console
  const someData = await getSmth()

  while (true) {
    const newInterval = 1000

    try {
      await getSmth()
    } catch (error) {
      console.error(error)
    }

    // in my case, I get an array of some elements and in a loop I run a different query for each of these elements
    for (let i = 0; i < 10; i++) {
      await getSmth()
    }

    await getSmth()
    await delay(newInterval)
  }
}

main()

@Jarred-Sumner, hi again

According to my observations, the script really crashes after the screen is locked or during somehow

by the way, I have 2 identical scripts running (let's imagine that I have 2 identical projects in different folders and work independently of each other) and as a rule only 1 crashes

Can you still reproduces it on v0.0.20? This looks like a issue that is already solved

I'll check this today

[scffs]

@cirospaciari

[scffs]

I got this error again xd @cirospaciari

[cirospaciari]

We added some fixes into sockets, can you try bun upgrade --canary and check if is still happening?
