Describe the Bug

Whenever I trigger a npm run build command, the node process hogs one core of my CPU and it freezes indefinitely. npm run dev works fine.

After a npm install next@canary, the outcome did not change.

Expected Behavior

An error message or a successful build.

To Reproduce

The project is public, so you can clone it:

git clone https://github.com/ntd/adg.entidi.com.git -b issue-32399
cd adg.entidi.com
npm install
npm run build --verbose

And this is what I get:

npm verb cli [ '/usr/bin/node', '/usr/bin/npm', 'run', 'build', '--verbose' ]
npm info using npm@8.3.0
npm info using node@v16.13.1
[ ... snip ...]

> build
> next build

(( ...emtpy... )) timing npm:load Completed in 21ms

... then the spinner stops and I cannot exit with CtrlC (I need to send a SIGKILL to the node process).

[ntd]

I just reduced my testcase. The following code triggers the issue:

import { visit } from 'unist-util-visit'
visit(whatever, '2', (node, _, parent) => {})

The full repository with the above code in lib/api.ts is in the issue-32399 branch.
