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?

In C, it's redundant, because void* can be implicitly casted to any type. It's like an Any, an Object, an object. It's sepples that sucks so much that even the ``Any'' type must be casted.
