The Closure Outlives The Frame

This queue runs each job later, from a worker thread.

#include <functional>
#include <string>
#include <vector>

void log(const std::string& tag, int n);
void run(std::vector<std::function<void()>>& jobs);

std::vector<std::function<void()>> jobs;

void enqueue(const std::string& name, int retries) {
    std::string tag = "job:" + name;
    jobs.push_back([&tag, retries] {
        log(tag, retries);
    });
}

int main() {
    enqueue("index", 3);
    enqueue("compact", 1);
    run(jobs);   // jobs invoked here
}

It works in a debug build and prints garbage tags in release. What is wrong?
