Shenanigans of ARM vs. Intel processor instructions, maybe? You got Rosetta installed? If so, have you made sure you’re running the ARM version of Erlang/Elixir?

thanks for answering!!
I don’t have Rosetta nope (or at least I wasn’t aware of it)
I was lucky enough that when I got the laptop this was already solved

Edit: running pgrep oahd returns me an int, so looks like I have it.. the problem is that I haven’t changed anything about the versions installed (aside from MacOS) recently, so that’s why I was wondering if the update was the problem..

I am experiencing exactly the same problem…
Any updates on a potential fix?

Thanks!

Not yet.. Looks like not many people is upgrading so we don’t have much visibility..
I hope someone gives us some light on this soon

We don’t test under Rosetta (we only test native Intel JIT or native ARM JIT), so it’s possible that we missed something.

If someone could build from source and run bin/cerl -lldb and give us a view of the crash, that would be of great help.

Hey @jhogberg ! Thanks for trying to help us
I’ve just installed Erlang from source and it works correctly and without any errors (even in the smoke test).
Looks like this error could be coming then from ASDF and brew binaries maybe?
I will try now installing Elixir from source too!

Edit: Same for Elixir! Installing from source makes it work as expected.
@Raf1 you could do the same as a workaround for now

Let me know if I can do something to give you insights about non-source installations

Pasting here the smoke test results

asdf also builds Erlang from sources.

If you could attach lldb to the binaries that crash that’d also be helpful.

Yes, so it’s rather strange that one works and the other does not. Perhaps asdf runs under Rosetta for some reason?

How could I do that?
When I run bin/cerl -lldb as you said before, I don’t get any error, just the following:

$ bin/cerl -lldb
