Description
Code
Unfortunately the ICE happened during some major refactor, and I only noticed some rustc-ice-... files later, so I can't really reproduce it (although it apparently ICE'd 5 times in short succession and produced 5 of these files). I suspect the code reported in these files was this derive line:
#[derive(Clone, Debug, Ord, PartialOrd, Eq, PartialEq, Hash)]
pub enum VariantKind {
Unit(usize),
Typed(Box<Type>),
}Meta
