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?

This is the way things work in C, dickbag.

It will work depending on your compiler implementation.  Every C compiler that I know of manages the heap by address.  So free() doesn't care what variable name you pass to it, only what address it points to.
