[shim] Uncatchable terminate called after throwing an instance of 'std::runtime_error'

[ronanjs]

When launching an application linked with the SHIM, and if openperf server is not ready, the application will crash with:

terminate called after throwing an instance of 'std::runtime_error'
  what():  Could not connect to socket server: No such file or directory

It does not seem to be possible to catch this error. I tried this, but it did not work:

int main(int argc, char const* argv[])
{
    sleep(1);
    bool connected = false;
    while (!connected) {
        try {
            int sd = socket(AF_PACKET, SOCK_RAW, htons(ETH_P_ALL));
            if (sd < 0) {
                perror("socket(AF_PACKET, SOCK_RAW)");
                sleep(1);
            } else {
                connected = true;
                close(sd);
            }
        } catch (std::runtime_error& e) {
            std::cout << "Failed to open the socket: " << e.what();
            sleep(1);
        }
    }

    printf("Starting the server...\n");
