I upfront apologize for not being able to create a minimum reproducible sample. I tried incrementally to recreate this behavior by creating code from scratch, but wasn't able to. This seems to be triggered by an interaction with ouroboros, but when an inner struct changes (but not always, just under some specific set of circumstances I can't pin down). Please let me know if more information is needed to understand what's happening.

Code

While trying to understand the issue, I created this struct based on an example in the ouroboros docs (which worked), and slowly modified to approach what I had that caused the crash. I built it in a separate mod and everything worked (I could freely modify the struct without issues, while still using it in an ouroboros struct). I then moved it into the same mod as my failing struct and switched it out for the struct causing errors in Context. Now, if I try to modify the struct (add a field, change a name, anything), the ICE happens. However, as is, it will compile. This happened in 1.72 nightly, so I tried upgrading to nightly today, but no go. If I make changes, cargo clean and cargo build, it'll work.

<code>
pub mod rec {
      pub struct ComplexData<'a> {
	      pub r#type: std::collections::BTreeMap<def::QualifiedName, u64>,
	      pub l2: Vec<crate::rec::Type<'a>>,
      }
}

#[self_referencing]
pub struct Context<'a> {
	def: &'a def::namespace::Namespace<def::DefaultTypeDecl>,
	#[borrows(def)]
	#[covariant]
	complex_data: crate::rec::ComplexData<'this>,
}
