Curl Easy segmentation fault with requests to external site

Thank you for this library :). Please let me know if any other information would help.

Describe the bug

I get a segmentation fault when I try to send a request using Curl Easy to an external site such as

• https//www.google.com.au

There is no issue with localhost/127.0.0.1.

I discovered this when trying to send requests using sync-request-curl in the specific environment with the following inside a Dockerfile:

FROM php:8.1.8-fpm-alpine
RUN apk add --update npm=7.17.0-r0 --repository=http://dl-cdn.alpinelinux.org/alpine/v3.14/main

It seems to work with no issues locally and with other base images, e.g. node:18-alpine.

This was just an environment that was configured at my workplace.

To Reproduce

Code that causes segfault (click to view)

import { Curl, Easy } from 'node-libcurl';

/*
 * Simplified from [sync-request-curl](https://github.com/nktnet1/sync-request-curl)
 */
const request = (method: string, url: string) => {
  const curl = new Easy();
  curl.setOpt(Curl.option.CUSTOMREQUEST, method);
  curl.setOpt(Curl.option.URL, url);
  curl.perform();
  const statusCode = curl.getInfo('RESPONSE_CODE').data as number;
  curl.close();
  return { statusCode };
};

const localUrl = 'http://localhost:3000';
console.log(`Sending GET request to '${localUrl}' (should get 200)`)
const response = request('GET', localUrl);
console.log('Status Code:', response.statusCode);

console.log();

const externalUrl = 'https://www.google.com'
console.log(`Sending GET request to '${externalUrl}' (gets SEGFAULT)`)
const segfault = request('GET', externalUrl);
console.log('Status Code:', segfault.statusCode);

Docker image here. Full repository here.

Have the local server running on one terminal

$ npm start

Then in another terminal run src/request.ts with

$ npm test

> test
> ts-node src/request

Sending GET request to 'http://localhost:3000' (should get 200)
Status Code: 200

Sending GET request to 'https://www.google.com' (gets SEGFAULT)
Segmentation fault
