### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Version gcc version 4.8.2 20140120 (Red Hat 4.8.2-16) (GCC) pulsar cpp client version 2.11 ### Minimal reproduce step #include <pulsar/Client.h> #include <thread> #include "report.h" #include <iostream> #include <thread> #include <memory> #include <cstring> #include <functional> #include <cmath> #include <ctime> #include <stdio.h> using namespace pulsar; using namespace std; void func(ReportClient* c, shared_ptr<string> resid) { c->Stop();// when I add this line, this program will core, after remove this line, this program works fine } int main(){ ReportClient j; shared_ptr<string> t; Client client("pulsar://xxx"); Producer producer; Result result = client.createProducer("topic_xxx", producer); if (result != ResultOk) { std::cout << "Error creating producer: " << result << std::endl; return -1; } } ### What did you expect to see? works ### What did you see instead?
