Segmentation fault when using AWS CDK lib

[acollins1991]

How can we reproduce the crash?

Create a Bun runtime project with the 'JavaScript/TypeScript code that reproduces the crash' code, updating PATH TO FILE to a file to build.

To get the exact scenario this script should be run using 'bun test' inside a monorepo setup, but have not tested if this is necessary.

The failure seems to occur when this line is run;

const code = props.code.bind(this);

in node_modules/aws-cdk-lib/aws-lambda/lib/function.js (https://github.com/aws/aws-cdk/blob/c1a3075c697b9673980315cab21cba0eea18782c/packages/aws-cdk-lib/aws-lambda/lib/function.ts#L912)

JavaScript/TypeScript code that reproduces the crash?

import * as cdk from "aws-cdk-lib";
import type { IFunction } from "aws-cdk-lib/aws-lambda";
import * as lambda from 'aws-cdk-lib/aws-lambda';
import { Construct } from "constructs";
import path from "path"

const bunFunction = await Bun.build({
  entrypoints: [PATH TO FILE],
  outdir: 'dist',
  target: 'bun',
  minify: true,
  external: ["*"]
})

export class BunCdkStack extends cdk.Stack {
  constructor(scope: Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    const fn: IFunction = new lambda.Function(this, 'HelloHandler', {
      code: lambda.Code.fromAsset(path.dirname(bunFunction.outputs[0].path)),
      handler: 'index.handler',
      runtime: lambda.Runtime.PROVIDED_AL2,
    });
  }
}
