Segmentation fault in Node 22.7.0+

[louh]

🐛 bug report

When running parcel (either in build or watch mode) in Node 22.7.0 or later, the command will crash with a segmentation fault error.

🎛 Configuration (.babelrc, package.json, cli command)

n/a -- this occurs even on no configuration.

🤔 Expected Behavior

Application should build or run.

😯 Current Behavior

Parcel crashes:

(I have also included a portion where downgrading to 22.6.0 demonstrates a working scenario.)

💁 Possible Solution

Unknown, but only workaround I have is to pin node versions on 22.6.0 or below for the time being.

🔦 Context

This occurs both building locally and this also fails when deploying on Heroku.

💻 Code Sample

This occurs for my own project, but I have also created a very basic test case using the quick-start instructions https://parceljs.org/getting-started/webapp/ -- which I am hosting here: https://github.com/louh/parcel-segfault

You can run this repository (make sure your local node version matches) with:

npm install
npx parcel src/index.html

Note that if you downgrade node to 22.6.0 the build will succeed as expected.

🌍 Your Environment

Software	Version(s)
Parcel	2.12.0
Node	22.7.0
npm/Yarn	10.8.2
Operating System	MacOSX Sonoma 14.6.1 and Heroku (NodeJS buildpack)

I have just noticed #9926. Related?

bumping this. I also have this error with node 20 LTS

This was fixed in Node 22.10
