# Reproduce code

```
#include <vector>
#include <string>
#include <coroutine>
#include <boost/asio.hpp>

#define REPRODUCE_ISSUE 1

boost::asio::awaitable<void>
test1(boost::asio::io_context& ioc) {
    co_await boost::asio::post(
        ioc,
        boost::asio::append(
            boost::asio::use_awaitable,
            std::vector<int> {
                1, 2, 3
            }
        )
    );
}

boost::asio::awaitable<void>
test2(boost::asio::io_context& ioc) {
    std::vector<std::string> str{ "aaa", "bbb" };
    co_await boost::asio::post(
        ioc,
        boost::asio::append(
            boost::asio::use_awaitable,
#if REPRODUCE_ISSUE
            std::vector<std::string> {
                "aaa", "bbb"
            }
#else
            str
#endif
        )
    );
}

int main() {
    boost::asio::io_context ioc;
    boost::asio::co_spawn(ioc, test1(ioc), boost::asio::detached);
    boost::asio::co_spawn(ioc, test2(ioc), boost::asio::detached);
    ioc.run();
}
```

The error happens only if I passed temporary std::vector<std::string> variable
to the function coming after co_await (test2).
If I use non temporary variable then no errors occurred (You can test it by
seting macro REPRODUCE_ISSUE 0.
If I use temporay std::vector<int>, no errors occurred (test1).

Here are godbolt result:

x86-64 clang 16.0.0
-std=c++20
https://godbolt.org/z/qnWqrcPKc

The same error is reported.



x86-64 clang 13.2
-std=c++20
https://godbolt.org/z/K74G65Yb1

No errors are reported.
