Singleton initializer issue

[pipawoz]

Hi, im trying to do something similar to the recv_header.cpp example but inside of a class.

I have no issue with compile/link but when running my class i get memory issues here:

// curl_interface.h
// Implementation of the singleton initializer
template<class T> curl_interface<T>::global_initializer::global_initializer(const long flag) {
    const CURLcode code = curl_global_init(flag);
    if (code != CURLE_OK) {
        throw curl_easy_exception(code,__FUNCTION__);
    }
}

Exception has occurred: W32/0xC0000374
Unhandled exception at 0x00007FFCC208F199 (ntdll.dll) in main.exe: 0xC0000374

My class is like:

class CurlCppClient
{
  private:
    std::ostringstream body_var;
    std::ostringstream header_var;
    curl::curl_ios<std::ostringstream> body;
    curl::curl_ios<std::ostringstream> header;
    curl::curl_easy curl_handler;
    ....
  public:
    ...
}

CurlCppClient::CurlCppClient()
  : body{header_var}, header{body_var}
{
  curl_handler.add<CURLOPT_WRITEFUNCTION>(header.get_function());
  curl_handler.add<CURLOPT_HEADERDATA>(header.get_stream());
  curl_handler.add<CURLOPT_WRITEDATA>(body.get_stream());
  ...
}

I have no issue if I only use one std::ostringstream like in easy_info.cpp but once i add the second std::ostringstream (even if i dont set the write function) it fails at the singleton.

Any ideas?

Can you upload all you code?
