Segmentation fault 11 when reading a CSV file in C ++

Good evening, everyone! Next, I made this code from a response here from the stack overflow and it is giving segmentation fault 11 in the last line of the file, somebody help me to solve, please! This is my code:

#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include <sstream>

using namespace std;

void read_archive(const char *in) {
ifstream file(in);
string buffer;
vector <vector<string> > linhas; //Vetor de vetor para todas as linhas
while(!file.eof()) {
    getline(file, buffer);
    stringstream ss(buffer);

    vector<string> linha;
    while(getline(ss, buffer, ';')) {
        linha.push_back(buffer);

    }
    linhas.push_back(linha);
}

    vector<unsigned long> ColunasRelevantes; //ColunasRelevantes[X];

    for(size_t i = 0; i < linhas[0].size(); i++) {
        string nomeColunas = linhas[0][i].substr(1, linhas[0][i].size() - 2); //Tirar as 2 aspas
        if(nomeColunas == "SG_PARTIDO") {
            ColunasRelevantes.push_back(i);
        }
    }

    for(size_t i = 0; i < linhas.size(); i++) {
        for(size_t j = 0; j < ColunasRelevantes.size(); j++) {
            unsigned long Coluna = ColunasRelevantes[j];
            string texto = linhas[i][Coluna].substr(1, linhas[i][Coluna].size() - 2);
            cout << texto << "\t";
        }
        cout << endl;
    }
}
int main () {

    read_archive("consulta_cand_2018_BR.csv");
    return 0;
}
