Rust 使用启用优化的 alloc 会导致非法指令崩溃

以下是铁 rust 代码:

use std::alloc;

fn main() {
    let name = String::from("a");
    let obj = unsafe { GcObject::allocate(name) };

    println!("{:?}", obj.object);
}

pub struct GcObject {
    object: *mut Object,
}

impl GcObject {
    pub unsafe fn allocate(object: String) -> Self {
        let layout = alloc::Layout::new::<Object>();

        // Allocate the object
        let ptr = alloc::alloc(layout) as *mut Object;

        if ptr.is_null() {
            eprintln!("Alloc error!");
            alloc::handle_alloc_error(layout);
        }

        *ptr = Object { kind: object };

        GcObject { object: ptr }
    }
}

struct Object {
    kind: String,
}

Rustc version: rustc 1.70.0 (90c541806 2023-05-31)
Platform: Fedora Linux 38

When compiled with following runs fine:
rustc main.rs -C opt_level=0

But when compiled with optimizations enabled like:
rustc main.rs -C opt_level=3
Causes a crash when run with the following message:

Illegal instruction(core dumped)个

那么，有没有办法解决这个问题，或者我的代码有问题.
