This part of code is giving SIGABRT error.please help what is wrong with this

vector v(170,0),v1(830,0);v[0]=1;
int k=1,p=0;
//store primes in v1//store composite in v1
for (int i = 2; i <= n; i++) {
if (isPrime(i)) {

isPrime () is another function which returns if I is prime or not

I think declaration of vector is not correct.
vector <data type> v(n,x); this creates vector of size n all initialized to x.

Or the code is storing too much memory.
