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`:
Using built-in specs.
