An int object consumes more than 12 bytes of memory. It depends on the
system architecture, too. It's usually 16 bytes on a 32bit system and 24
bytes on a 64bit system.
The actual size can be computed by sizeof(ptr) + sizeof(long) +
sizeof(ssize_t). The size is rounded up to the next multiple of 8 bytes
due to address alignment.
