Please, lets not discuss the `@allocated` issue in this thread. I created a separate thread for that issue: [@allocated does not work on Julia 1.12rc1](https://discourse.julialang.org/t/allocated-does-not-work-on-julia-1-12rc1/131553) To reproduce the GC issue, do

```julia-auto
git checkout 14fcb0e5ad3216aef2715ccc325a58d7a449e4b1

```
