Build breaking when importing JSBI in 13.5.4

[jeremypress]

Link to the code that reproduces this issue

https://github.com/jeremypress/next-issue-repro

To Reproduce

1. run the application (this runs a built version of the app) https://replit.com/@jeremy/next-1354
2. notice the client side error
3. run the app on 13.5.3 https://replit.com/@jeremy/next-1353
4. notice no errors

Relevant code:

import '../styles/globals.css'
import type { AppProps } from 'next/app'
import JSBI from 'jsbi';
const modulePath = require.resolve('jsbi');
console.log(modulePath);


function MyApp({ Component, pageProps }: AppProps) {
  const x: JSBI = JSBI.BigInt(Math.floor(Math.random() * 10000));
  console.log(x);
  return <Component {...pageProps} />
}

export default MyApp

This package is linking to UMD via the "browser" entry, which isn't great, but something changed behavior wise between next 13.5.3 and next 13.5.4

Current vs. Expected behavior

Following reproduction steps,
I did not expect this type error

TypeError: Cannot call a class as a function

Additional context

I tried to original submit this with a repl, which I think should be a valid way to submit bugs 🤷🏻

I was going to create a separate issue for this but seems we're having the same problem. Attaching my repro here:

This is a regression between swc_core@v0.83.12 and swc_core@v0.83.28

next.js/Cargo.lock

Lines 6661 to 6663 in 76e06d5

	[[package]]
	name = "swc_core"
	version = "0.83.12"

next.js/Cargo.lock

Lines 5811 to 5813 in 1e8dca4

	[[package]]
	name = "swc_core"
	version = "0.83.28"

Thanks for the quick look @kdy1

The cause was a bug related to the new mangling option. I'll fix it soon and will send a PR, hopefully today.

The new mangling option was added in #56281 to align with terser
