Indexing std::vector

I want to run a simple program in C++ in which there are two vectors - one is a std::vector<int> and the other is a std::vector<bool> of equal length. The value of the boolean vector at an index decides whether the value of the integer vector will be printed or not. Here is a copy of the program I am trying to run:

#include<bits/stdc++.h>
using namespace std;

int main(){
    vector<int> arr{1, 2, 3, 4, 5};
    vector<bool> b(true, arr.size());

    for(int i=0; i<arr.size(); i++){
        if(b[i])
            cout<<arr[i]<<endl;
    }
    return 0;
}

The above program runs as expected. But there is an Address Boundary Error encountered when I change the values from true to false in the std::vector initialization line. Precisely, the error is:

fish: Job 1, './test_vector_bool' terminated by signal SIGSEGV (Address boundary error)

I am already aware of some of the major pitfalls of using vector<bool> from these threads:

• Is the use of std::vector objects in C++ acceptable, or should I use an alternative?

• Is vector < bool > really so bad?

What I gathered from these threads is we should not be using reference for vector<bool> in cpp. But all I need to know is why is the vector with true working and initialization with false failing?
