malloc() and free()

#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?

I'm just being cute and tsundere. Here you are. Now please remember the frightening power of cache, and try to stay on its good side.
