malloc() and free()

Name: Anonymous 2011-01-18 22:44

#include <stdlib.h>

int * b;

int main(void)
{
    int * a = NULL;
    a = (int *) malloc(sizeof(int));
    b = &a;
    free(b);
    return 0;
}


Would this result in a memory leak? If yes, why?

int main(void)
{
    int * a = NULL;
    a = (int *) malloc(sizeof(int));
    b = a;
    free(b);
    return 0;
}


I still don't trust this code. Can someone elaborate.
