(epmd segfaults when trying to bind inet in gha ubuntu. ugh.)

resolves #342

Whats the status of this PR? I am interested in adding elixir-lang, but need erlang for it.

Stalled for erlang segfaulting. Feel free to look at it, if you want.

Hi @jhheider,

I've done some experiments. I noticed that the only pipeline that fails, is using a pipeline hosted by GitHub, while the other ones are self-hosted.

I have tried to run the tests locally inside a container using the ubuntu:latest image and the tests passed as expected.

The error message we see in the CI means that the beam cannot connect to epmd. I guess the segfault we see is also from epmd which cannot start. The escript executes fine, but returns econnrefused.

epmd, by default, is binding to the public interface (0.0.0.0), it's possible that this is not allowed inside a Github CI runner? I couldn't find any resource/docs about that.

So one test I would suggest is to add -kernel inet_dist_use_interface {127,0,0,1} inside the test script. If this doesn't work we could try starting epmd as a test with the debug flag (epmd -d).

let's try it. it seemed like maybe it was trying to create docker instances, which might be a problem.

Part of it was segfaults on x86-64 without PIE (as we often see in compiled C). Passing now.

beautiful work

Guess we now need https://hex.pm
