segmentation fault on exit when auto-reconnect is true

[kiranpradeep]

Below redis client program seg-faults on exit if redis-server is not available. I killed redis-server after the client started. Call stack from core dump is below.

#include <cpp_redis/cpp_redis>
#include <thread>
#include <chrono>

int main(void) 
{
  cpp_redis::client client;
  client.connect("127.0.0.1", 6379, nullptr, 0, 10, 1000);
  std::this_thread::sleep_for(std::chrono::seconds(5)); // kill redis-server during this sleep
  client.cancel_reconnect();
  return 0;
}
