AMQPException will crash in function AMQP::login()

[fan-chao]

Currently the AMQP::login() is as below.
void AMQP::login() { amqp_rpc_reply_t res = amqp_login(cnn, vhost.c_str(), 0, FRAME_MAX, 0, AMQP_SASL_METHOD_PLAIN, user.c_str(), password.c_str()); if ( res.reply_type != AMQP_RESPONSE_NORMAL) { amqp_destroy_connection(cnn); throw AMQPException(&res); } }

I use latest rabbit-c library and it has crash issue if login fails.
The reason is that cache buffer will be cleared in function amqp_destroy_connection(cnn). So the pointer of res.reply.decoded is invalid while execute AMQPException(&res) and causes the following codes to crash.
if(res->reply.id == AMQP_CONNECTION_CLOSE_METHOD) { amqp_connection_close_t *m = (amqp_connection_close_t *) res->reply.decoded; this->code = m->reply_code; sprintf(buf, "server connection error %d, message: %.*s", m->reply_code, (int) m->reply_text.len, (char *) m->reply_text.bytes ); }

I modify the order of the above two lines and it works.
if ( res.reply_type != AMQP_RESPONSE_NORMAL) { auto amqp_exception = AMQPException(&res); amqp_destroy_connection(cnn); throw amqp_exception; }
