Here's a valid Rust snippet:

fn main() {
    let mut range = 0..5;
    for num in &mut range {
        if num == 2 {
            break;
        }
    }

GCC 13.1.1 (Arch Linux) seems to mis-align __m512i vectors on the stack when -fsanitize=address is enabled. repro.c (below in this Gist) is a minimized repro. Compile it like this:

gcc repro.c -g -mavx512f -fsanitize=address

When I execute it I get the following:

$ ./a.out

AddressSanitizer:DEADLYSIGNAL
