Code

The code is part of the full_moon package, I have filed an issue there to try and get a minimal example

[hellow554]

I can't reproduce the ICE. Can you provide steps to reproduce it? Something like this:

git clone https://github.com/Kampfkarren/full-moon
cd full-moon
rustup override set nightly-2021-08-31
cargo build

[IndianBoy42]

I encountered this when trying to install stylua and selene.

cargo install stylua

Perhaps this only happens in release mode?

[hellow554]

cargo build --release is needed on the full-moon repository. I'm on it

[SNCPlay42]

Duplicate of #88498 (which in turn is a duplicate of #88307).

[hellow554]

Can confirm, that the code that produces the ICE is indeed the same.
This can therefore be closed.
