ICE：called Result::unwrap() on an Err value: ReferencesError(ErrorGuaranteed(()))

[sososopy]

Similar to problem #128094, it may be a duplicate problem, but the compile command is different
The issue compilation command I opened is -C opt-level=1, and #128094 is -Zmir-opt-level=5 --edition=2018
And the code is a little different, so I brought up the issue

Code

pub struct A {
    name:NestedOption<Option<String>>,
}
impl<'a> A {
    pub async fn func1(
    ) -> &'static A {
        static res: A =
            A { name: None };
        &res
    }
}
fn main() {}

error: the compiler unexpectedly panicked. this is a bug.
note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: please make sure that you have updated to the latest nightly

note: please attach the file at `D:\rust_test\test1\src\rustc-ice-2025-03-08T13_01_27-29596.txt` to your bug report

note: compiler flags: -C opt-level=1

query stack during panic:
#0 [optimized_mir] optimizing MIR for `<impl at .\ttt\test.rs:164:1: 164:11>::func1::{closure#0}`
#1 [layout_of] computing layout of `{async fn body of <impl at .\ttt\test.rs:164:1: 164:11>::func1()}`
... and 2 other queries... use `env RUST_BACKTRACE=1` to see the full query stack

[matthiaskrgr]

The flags do not make a difference here I think as both snippets crash with opt-level-1 and mir-opt-level=5
My guess is that in both cases we enable the GVN mir opt which then causes the underlying problem.

pub struct A {
    name:Option<String>,
}
impl<'a> A {
    pub async fn func1(
    ) -> &'static A {
        static res: A =
            A { name: None };
        &res
    }
}
fn main() {}

I don't understand why struct members change to this way and it doesn't generate ICE
