ICE: assertion failed: value <= (0xFFFF_FF00 as usize #2258
Description
I tried this code:
// run-pass
#![feature(extern_types)]
use std::mem::{align_of_val, size_of_val};
extern "C" {
type A;
}
#[kani::proof]
fn main() {
let x: &A = unsafe { &*(1usize as *const A) };
let _ = size_of_val(x);
}using the following command line invocation:
kani file.rs
with Kani version: 0.22.0
I expected to see this happen: explanation
Instead, this happened: explanation
warning: unused import: `align_of_val`
--> extern-types-size_of_val.rs:4:16

4 | use std::mem::{align_of_val, size_of_val};
