Bug ID: 115660
Summary: internal compiler error: in build_special_member_call,
at cp/call.cc:11085
Product: gcc
Version: 13.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: vipcxj at 126 dot com
Target Milestone: ---
```c++
do_async([]() -> asio::awaitable<void> {
using namespace cfgo;
close_chan closer {};
auto token = co_await get_token("1", "root.*", false);
auto signal = make_websocket_signal(closer,
cfgo::WebsocketSignalConfigure{
.url = fmt::format("ws://{}:{}/ws", SIGNAL_HOST, SIGNAL_PORT),
.token = token,
.ready_timeout = std::chrono::seconds(30),
});
{
co_await signal->join(closer, {"root.room1"}); // this line
EXPECT_EQ(1, signal->rooms().size());
EXPECT_TRUE(signal->rooms().contains("root.room1"));
}
});
```
I think the initializer_list in the await expr cause the crash.
full error:
