Description of problem:

valgrind reports memory leaks in simple C program using libgfapi

Version-Release number of selected component (if applicable):
3.8.3 (and I believe all previous versions, 3.8.X , 3.7.X , ...)

How reproducible:

just run valgrind on a compiled program

Steps to Reproduce:
1. simple C code:

# cat hellogluster-basic.c
#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <stdlib.h>
#include <string.h>
#include <glusterfs/api/glfs.h>

int main (int argc, char** argv) {
        glfs_t *fs = NULL;

        fs = glfs_new ("pool");
        if (!fs) {
          fprintf (stderr, "glfs_new: returned NULL\n");
          return 1;
        }

        glfs_fini (fs);

        return 0;
}


2. compile 

gcc hellogluster-basic.c -lgfapi

3. run valgrind
