"segmentation fault"

🕗 Version & Regression Information

• This is a crash

⏯ Playground Link

https://github.com/remarkjs/remark/tree/main/packages/remark-parse

💻 Code

The code is not actually relevant. It still happens if you remove the content of packages/remark-parse/lib/index.js. The existence of the file is important.

🙁 Actual behavior

Using Node.js 22, running tsc --build from the remark-parse workspace, yields:

$ tsc -b     
[1]    57135 segmentation fault (core dumped)  tsc -b

🙂 Expected behavior

It generates type definitions

Additional information about the issue

It works in Node.js 20, but not Node.js 22.

If the project is built with Node.js 20, then an incremental build with Node.js 22 won’t crash TypeScript.

Neither tsc nor tsc --showConfig not tsc --build --clean causes a crash, only tsc --build.

See remarkjs/remark#1291 (comment) for some more info where this was first discovered.
