Weird bug?

[jnbrq]

void priorities()
{
    fmt::println("test: priorities");

    auto coro = []() -> coroutine<>
    {
        auto coro1 = []() -> coroutine<>
        {
            co_await timeout(2);
            fmt::println("coro1 done");
        };

        auto coro2 = []() -> coroutine<>
        {
            co_await timeout(2);
            fmt::println("coro2 done");
        };

        co_await (coro1() || coro2());
        fmt::println("coro done");
    }();

    environment env;
    env.bind(coro);

    try
    {
        env.run();
    }
    catch (std::exception &ex)
    {
        fmt::println("[asynchronous] Exception: {}", ex.what());
    }
}
