            Bug ID: 111651
           Summary: Specific syntax with C++ 20 designated initializers
                    and coroutines breaks
           Product: gcc
           Version: 13.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: yunus at ayar dot eu
  Target Milestone: ---

The error 'internal compiler error: in build_special_member_call, at
cp/call.cc:11093' occurs in this code:

```cpp
awaitable<void> make(boost::asio::any_io_executor executor)
{
  co_await wdlite::async_new_session(executor, "http://localhost:9515",
                                    
wdlite::capabilities::make(wdlite::capabilities::Capabilities{
                                       .browser_specific =
                                         wdlite::capabilities::ChromeOptions{
                                           // The next line is not ok.
                                           .arguments = { std::to_string(0) },
                                           // The next line is ok.
                                           // .arguments = { "ok" },
                                         },
                                     }),
                                     use_awaitable);
  co_return;
}
```

If I substitute `.arguments = { std::to_string(0) },` with `.arguments = { "ok"
},` the code compiles just fine. `.arguments = { std::to_string(0) },` is not a
problem if I remove the `co_await` keyword. My Boost version is 1.80 and the
Boost.ASIO is 1.24.

The output of `g++ -v`:
