ICE "no entry for node id" (new_named_lifetime_with_res in rustc_ast_lowering) · Issue #103210 · rust-lang/rust (original) (raw)
Found by fuzzing with a modified fuzz-rustc
Code
The compiler panics while compiling this code (playground).
It then panics a second time while trying to explain why it panicked.
struct S { _t: T }
fn f(S::<&i8> { .. }: S<&i8>) { }
fn main() { f(S { _t: &42_i8 }); }
I believe this is a valid Rust program, based on the variants below that compile successfully.

It compiles successfully if I change &i8 to _ in the paramter's pattern:
struct S<T> { _t: T }
fn f(S::<_> { .. }: S<&i8>) { }
fn main() {
f(S { _t: &42_i8 });
}
It also compiles successfully if I change the reference to specify the 'static lifetime throughout:
