maybe execve. the loader/linker (ld in linux) are responsible for loading the address. I think with fork they are not re-loaded but it copies (clones page tables/pages etc?) the addr space. Also, if you print your addrs in hex: '0x5fdbbf654600' you can see its aligned to some place. if you'd do number >> 8 it will be '0x005fdbbf6546' which might be more useful if you don't want the least significant bits to be all unset in your random value.
