hi guys,

i have written simple program for testing curl example.
but its display some memory leak errors.
if u anybody know this problem solution reply me.
its display "*still reachable: 288 bytes in 8 blocks." error

**program code :* curl.c

#include <curl/curl.h>
int main(void)
{
        CURL *curl;

        curl = curl_easy_init();

        curl_easy_cleanup(curl);

        curl_global_cleanup();

        return 0;
}

*Compile :* gcc curl.c -lcurl -g
*Run :* valgrind --show-reachable=yes --leak-check=full ./a.out
*Output :*
