segfault with node v12.19.0

rclnodejs segfaults after a few seconds after receiving a subscription. It only happens with node v12.19, works fine in v12.18.4.

To reproduce:

const rclnodejs = require('rclnodejs');

async function main() {
  await rclnodejs.init();
  const node = rclnodejs.createNode('test');
  rclnodejs.spin(node);
  
  node.createSubscription('std_msgs/msg/String', 'test', {}, console.log);

  const pub = node.createPublisher('std_msgs/msg/String', 'test');
  pub.publish({ data: 'hello' });
}

main();

Output:

$ node test.js 
{ data: 'hello' }
Segmentation fault (core dumped)

I got that as well, I think it’s unrelated, it seems more like some v8 changes that causes it instead.

Btw, the offending commit that causes v12.19 to fail has been identified and I think they will be backporting the fix in the next release. I’ll go ahead and close this issue.

https://github.com/nodejs/node/issues/35620 It looks like someone else has the same problem (I got the same stack trace).
