It works on my machine?

compiler-errors · 2024-06-27T02:18:01Z

@Jules-Bertholet: That's a debug assertion. You need to add:

rust.debug = true

To your config.toml, since debug assertions are not enabled by default even for the "compiler" profile.

Under gate `ref_pat_eat_one_layer_2024_structural`. Enabling `ref_pat_eat_one_layer_2024` at the same time allows the union of what the individual gates allow.
