Sounds good.

Then you could just do something like

        void *ptr = (void *)ALIGN_UP((unsigned long)*p, 8);
        *p = ptr + size*n_memb;
        return ptr;

and that would be a lot simpler.

Well, if 8-byte alignment doesn't work, then the existing code (with
the fix) doesn't work either, so..
