Re: Memory leak in libcurl

Hi Dan,
The memory leak is reported even if curl_global_cleanup() is called.
This is true whether I call curl_global_init directly or indirectly.
The code below reports a memory leak

#include <iostream>
#include <curl/curl.h>
#include <crtdbg.h>

#define _CRTDBG_MAP_ALLOC

int main(int argc, char *argv[])
{
  CURL *curl;

  curl_global_init(CURL_GLOBAL_ALL|CURL_GLOBAL_WIN32);

  curl = curl_easy_init();

  curl_easy_cleanup(curl);

  curl_global_cleanup();

  if (_CrtDumpMemoryLeaks())
          std::cout << "Memory Leak" << std::endl;
  else
          std::cout << "No memory leak found" << std::endl;

  return 0;
}
