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

	import time
	from blake3 import blake3
	from hashlib import sha256, sha512, blake2s

	input_bytes = b"hello world"
	print(f"input bytes: {input_bytes}")
	warmup_iterations = 1_000
	measure_iterations = 1_000_000

	#include <errno.h>
	#include <stdio.h>

	// We want a function that creates a couple files. Here's the naive approach:

	int hardcoded_cleanup(const char path1, const char path2) {
	FILE *file1 = fopen(path1, "w");
	if (file1 == NULL) {
	return errno;
	}

	#include <iostream>
	#include <mutex>
	#include <thread>
	#include <vector>

	template <typename T> class MyMutex;
	template <typename T> class MyMutexGuard;

	template <typename T> class MyMutex {
	friend class MyMutexGuard<T>;
