a simple rpclib server will eventially crash after ~1000 consecutive connections.
Looks like the server doesn't properly release the connection to a client after client goes out of scope. How would I properly close the client?

test_leak crashes, test_no_leak doesn't crash.

void test_leak(){
  for(int counter=0; ; counter++){
    rpc::client client(host, port);
    auto response = client.call("fun", "arg").as<string>();
  }
}

void test_no_leak(){
   rpc::client client(host, port);
   for(int counter=0; ; counter++){
     auto response = client.call("fun", "arg").as<string>();
  }
}

• ls -l /proc/$pid/fd | wc -l keeps increasing
• htop shows memory keeps increasing
• lsof -p $pid keeps increasing, showing entries such as:

binary $pid user  ...     IPv4 ...      0t0      TCP localhost:18700->localhost:39692 (ESTABLISHED)

EDIT:
for the server, use this for eg:bind("fun", []() { return ""; });
