out_of_bounds_indexing false positive #1668
Description
This comes from a code reduction, so it's reasonable in its original context:
#![allow(unused_variables)]
fn main() {
const N: usize = 1_000;
let data = [0, 0, 0, 0];
if N <= 4 {
let result = data[N - 1];
}
}error: index out of bounds: the len is 4 but the index is 999
--> src/main.rs:6:22
|
6 | let result = data[N - 1];
| ^^^^^^^^^^^
