hi @JacobMao !
can you report your piece of code? Without knowing how you are using curlcpp's perform() function, I really don't know how to help-

[JacobMao]

ok.

my piece of code:
try {
easy.perform();
} catch (curl_easy_exception error) {
}

these codes are inside a member function of class, and I create instance of the class in various multithreading.

@JacobMao without the entire piece of code I can't help you. I can not reproduce the problem. Does xCode reports you a null pointer? What is happening?

[JacobMao]

I found this function in curl_exception.cpp file:
curl_exception::curl_exception(const std::string &error, const std::string &fun_name) { curl_exception::traceback.insert(curl_exception::traceback.begin(),curlcpp_traceback_object(error,fun_name)); }

because traceback is a static member variable of curl_exception, Is it threadsafe that use function of insert in multithreading environment?

@JosephP91 hello?

[JosephP91]

Hi @JacobMao, sorry for the delay in the response. Yes, it couls be, since curlcpp is not thread safe yet. I have accepted your pull request. Is the problem solved? Let me know!

[JacobMao]

Yes, it's solved. Thanks for your response.
