Internal compiler error "node_id_to_type: no type for node" with save-analysis

[evestera]

Compiling the code below with rustc point2.rs -Zsave-analysis resulted in an internal compiler error.

I've tried to minimize the code. Removing either the derive, the other two structs or fixing the lifetime error in NestedA makes the panic disappear.

Code

#[derive(Debug)]
struct Point {
}

struct NestedA<'a, 'b> {
    x: &'a NestedB<'b>
}

struct NestedB<'a> {
    x: &'a i32,
}

fn main() {
}

Output with backtrace

error[E0491]: in type `&'a mut NestedB<'b>`, reference has a longer lifetime than the data it references
 --> point2.rs:6:5
  |
6 |     x: &'a mut NestedB<'b>
  |     ^^^^^^^^^^^^^^^^^^^^^^
  |
note: the pointer is valid for the lifetime 'a as defined on the struct at 5:0
 --> point2.rs:5:1
  |
5 | struct NestedA<'a, 'b> {
  | ^
note: but the referenced data is only valid for the lifetime 'b as defined on the struct at 5:0
 --> point2.rs:5:1
  |
5 | struct NestedA<'a, 'b> {
  | ^

note: the compiler unexpectedly panicked. this is a bug.

This no longer ICEs, marking E-needstest.

This error occurred for me when compiling the code in an intermediate state where I expected errors. It is still a small project so I checked in the offending code here:

neallester/danake-rs@aeb9b12
