Further minimized

struct Node<const D: usize> {}

😆 I only thought I fixed it, but I didn't after all, I just hid it. My new minimization still ICEs after my change.

Another one

struct IteratorOfWrapped<T, I: Iterator<Item = T>>(I);

fn recurse<T>(elements: T) -> Vec<char> {
    recurse(IteratorOfWrapped(elements).map())
}
