Bun index out of bounds error when used with aws cdk

[NimmLor]

How can we reproduce the crash?

Bun v1.1.8 on Windows using Powershell.

1. Setup a simple cdk project

2. Run bunx cdk synth ./bin/infrastructure.ts
   Note: adding the --bun flag adds a CDK warning that CDK is not tested with the given node version (defaults to the latest even though its not installed)

JavaScript/TypeScript code that reproduces the crash?

import { App, CfnOutput, Stack, type StackProps } from 'aws-cdk-lib'
import type { Construct } from 'constructs'

class SampleStack extends Stack {
  public constructor(scope: Construct, id: string, props?: StackProps) {
    super(scope, id, props)

    new CfnOutput(this, 'Hello', {
      value: 'world',
    })
  }
}

const app = new App()
new SampleStack(app, 'InfrastructureStack', {})

Relevant log output

bunx cdk synth .\bin\infrastructure.ts
