Fix errors from gcc upgrade

Fix errors from gcc upgrade

- We know that the number of privacies is under 100 so it never will
exceed the length of counter but gcc determined it might cause a problem
so change the size of counter enough

- int can have [-2147483647, 2147483647] value and if it is printed as
char then it will use 1~11 bytes. We knew that privacy num will not exceed
2bytes so assined 10 bytes for counter. But gcc says it should be enough
size for 2 int and 3 byte chars, so I fixed the size of counter enough.
