Internal Compiler Bug

[dustinws]

Hello!

Today the compiler informed me that it encountered an internal compiler bug. I was just looking at the help output from roc --help and noticed the --dev flag. I tried to use it without any arguments, and then the crash happened.

I don't know if this is a bug, or just misuse.

Example

main.roc

app [main] { pf: platform "https://github.com/roc-lang/basic-cli/releases/download/0.15.0/SlwdbJ-3GR7uBWQo6zlmYWNYOxnvo8r6YABXD-45UOw.tar.br" }

import pf.Stdout

main =
    Stdout.line! "hello world!"

Then run roc --dev

The output is

An internal compiler expectation was broken.
This is definitely a compiler bug.

@dustinws can you confirm what os and arch you are running on, also did you use any linker flags --linker=legacy etc?

I'm just wanting to categorise this correctly and this information will be helpful for use in future.

This also happens on linux (NixOS): roc --dev examples/helloWorld.roc.

I recommend using roc dev instead @dustinws

• add a test after we fix this

@lukewilliamboswell
My OS: Arch Linux 6.10.9-arch1-2

I did not use any flags related to the linker. This happened in the first couple of minutes of installing the nightly release and it was one of the first things I did after roc dev and roc build.

@Anton-4
For sure, I'll use roc dev. I just saw the option and was curious.

Arch is x86_64, I didn't see that earlier in your comment.
