You guys are going off into the weeds. All that's required from C
for the byte[] strategy to work is that this works:

   void *ptr;
   char *buf;

   ptr = <any valid pointer value>
   buf = malloc(sizeof(ptr));
   memcpy(buf, &ptr, sizeof(ptr));

   ... then sometime later ...

   memcpy(&ptr, buf, sizeof(ptr));
   <continue using the fully restored ptr>

I'm not a specophile but I would guess that C does at least guarantee this.
