Quando inicio o server (rails s), faz o diagnostico habitual (Puma, etc...) mas depois ao inicializar o localhost, passados 5 segundos faz um print de uma lista extensa de diagnóstico, terminando com o seguinte erro:
ou may have encountered a bug in the Ruby interpreter or extension libraries.
Bug reports are welcome.

What environment are you on?

Note that a Rails app loads a fair amount of C extensions, every one of which could potentially cause this kind of error. To determine whether this is our issue, at least we need to know how ruby died. You can invoke the rails command as

rails s > rails-log.txt 2>&1

and after its termination the file rails-log.txt will contain information that we are interested in.

[1] 36345 IOT instruction (core dumped) rails s

The environment is Development

When i invoke the rails command as suggested, the only thing that shows is:
[1] 43536 IOT instruction (core dumped)
after i trigger localhost.

Como resolver?

Obrigado

I see you are using Visual Studio Code. We really would like to look at all the output in the TERMINAL tab shown in your screen shot, including everything before

[NOTE]
You may have encountered a bug [...]

though it may look mysterious to you. Would you please copy and paste (or attach) it here?

Hi
In the meanwhile, i got out of the branch i was working, created a new one to work on another feature and the error didn't come up... It was something on the other branch that was doing some glitch but now i can't figure it out. If the issue arises again i'll launch another ticket.
