uring statx failure
Stating a bunch of files in a git repo fails in a weird way.
It doesn't fail every time but in my checkout of https://github.com/git/git it fails about 30% of the time.
I invoke:
git ls-files | strace -o /tmp/stat-many.strace ~/Projects/git-dirty/stat-many $PWD
I have attached a failing strace.
I'm running a 5.7.17 kernel on amd64 with liburing 0.7 from Debian.

Why is this wrong?
#include <iostream>
#include <string>
#include <vector>
void test_string_vector() {
std::vector<std::string> v;
const char* one = v.emplace_back("one").data();
std::cout << "added one" << std::endl;
std::cout << "v.capacity() = " << v.capacity() << std::endl;
