Node Serialport crashes

[GriffinSauce]

What version of Bun is running?

1.0.0+822a00c4d508b54f650933a73ca5f4a3af9a7983 (congrats btw!)

What platform is your computer?

Darwin 21.6.0 arm64 arm

What steps can reproduce the bug?

Reproduction here

• bun install @serialport/bindings-cpp
• try to use serial port bindings, eg:

import { autoDetect } from "@serialport/bindings-cpp";

const Binding = autoDetect();
Binding.list();

This crashes with:

dyld[30366]: missing symbol called

What is the expected behavior?

The Node Serialport packages work as expected, the list command lists available serial ports etc.

What do you see instead?

Crash:

dyld[30366]: missing symbol called

Additional information

This package is the low-level interface for Node Serialport so I expect if this works the whole thing should. I suspect this issue has something to do with napi usage but I have 0 experience in this area.

It crashes with SIGSEGV when doing something like this:

import { SerialPort } from "serialport";

const sp = new SerialPort({
  path: "/dev/ttyUSB0",
  baudRate: 9600,
  autoOpen: true,
});

output: Job 1, 'bun src/index.ts' terminated by signal SIGSEGV (Address boundary error)

EDIT: using serialport version 12.0.0 (works with node on version 20)

This works for me in Bun 1.0.2:

$ bun install @serialport/bindings-cpp

import { autoDetect } from "@serialport/bindings-cpp"
const Binding = autoDetect()
console.log(await Binding.list())
// see a list correctly

But this doesn't (serialport is v12.0.0):

$ bun install serialport

import { SerialPort } from 'serialport'
const serial = new SerialPort({ path: '/dev/ttyACM0', baudRate: 115200, autoOpen: false })
serial.open((err) => console.log(err || 'success'))

Error shows as follows:

374 |       writable: !1,
375 |       configurable: !0
376 |     }), fn;
377 |   }
378 |
379 |   function fn() {
                             ^

Is this related to trustedDependencies somehow?

I've tried this but it didn't work for me when running the script with bun. It will work if you run with node so it's the runtime that is failing (not the install). It's been a while but I suspect you accidentally ran it with node. I can't make bun work with any permutation of the serialport libraries.

@Jarred-Sumner in #5452 you mention "serialport no longer crashes" but it does, the same reproduction applies. It might be worth mentioning that I'm running this on modern MBPs, I haven't checked whether Linux / Windows would run.

Thanks for looking into it so far!

Got no luck too

Bun is just quitting on me using the latest win 11 build.
