Hi,
I have a simple main program that is doing following things

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

using namespace std;

int main(int argc, char* argv[])
{
curl_global_init(CURL_GLOBAL_ALL||CURL_GLOBAL_SSL);
curl_global_cleanup();
}

I ran valgrind on this as
valgrind --tool=memcheck --num-callers=40 --show-reachable=yes
--leak-check=full sample 2>Valgrind.log

Here is the valgrind log :
