The MaxListenersExceededWarning warning is annoying but it's just a standard node warning. It'll be silenced by libp2p/js-libp2p#2417

I can't replicate this locally, though I'm using Mac OS X.

Segfaults are normally caused by native modules, there aren't many of these in the stack, node-datachannel is one (used by the WebRTC transport) - are you able to isolate where the segfault is coming from?
