rpc异常导致程序崩溃

[chenjinle]

程序异常时报错如下：
#0 0xb6a0ee22 in rest_rpc::rpc_client::call_back(unsigned long long, boost::system::error_code const&, boost::basic_string_view<char, std::char_traits >) () from /mnt/data/hwt_rk3308/lib/libbtl.so

用法是在libbtl库中使用rpc创建客户端提供接口，另外有一个服务端，客户端接口代码如下：
rest_rpc::rpc_client& getBoardRpcClient(const std::string &host, int port) {
static rest_rpc::rpc_client m_rpcBoardClient;
if (m_rpcBoardClient.has_connected()) {
return m_rpcBoardClient;
}
m_rpcBoardClient.enable_auto_heartbeat(); // automatic heartbeat
m_rpcBoardClient.connect(host, port, false, 60); // 60s
return m_rpcBoardClient;
}

int getKeyCodeStatus(const int nKeyCode, KEYVALUE &emKeyValue){
#ifndef __NOREST_RPC
rest_rpc::rpc_client &m_rpcClient = getBoardRpcClient();
int nRetValue = 0;
if (!m_rpcClient.has_connected()) {

		printf("Error:%s not connect\r\n", __FUNCTION__);
		return -2;
	}
	auto f = m_rpcClient.async_call<rest_rpc::FUTURE>("getKeyCodeStatus", nKeyCode);
	if (f.wait_for(std::chrono::milliseconds(5000)) ==
		std::future_status::timeout) {
		printf("Error: %s : call timeout, line: %d\n", __FUNCTION__, __LINE__);
		return -3;
	}
	nRetValue = f.get().as<int>();
	if(nRetValue < 0){
		return -4;
	}else{
		emKeyValue = (KEYVALUE)nRetValue;
		return 0;
	}
#else
    return 0;
#endif	
}

能提供一个完整的测试代码吗，包括服务端和客户端。
