Thread Breakpoint?

This loop is supposed to prompt the user for values from 1 to 6 until it has 5 values. It works for every other number, but if I enter a 2 it says "Thread1: breakpoint 1.1" then doesn't crash but stops accepting inputs. I am new to C++ so I may be missing something obvious syntax-wise.

 int userInput = 0;
 int numUserIns = 0;
 int diceRoll1, diceRoll3, diceRoll2, diceRoll4, diceRoll5, diceRoll6;

 int numOnes = 0;
 int numTwos = 0;
 int numThrees = 0;
 int numFours = 0;
 int numFives = 0;
 int numSix = 0;

while (numUserIns <= 5){
    cout << "Enter a number from 1 to 6\n";
    cin >> userInput;
    if (userInput == 1){
        diceRoll1 = userInput;
        numUserIns++;
        numOnes++;
    } else if (userInput == 2){ //not accepting two as input
        diceRoll2 = userInput;  //This line causes error: Thread 1: breakpoint 1.1
        numUserIns++;
        numTwos++;
    } else if (userInput == 3){
        diceRoll3 = userInput;
        numUserIns++;
        numThrees++;
    } else if (userInput == 4){
        diceRoll4 = userInput;
        numUserIns++;
        numFours++;
    } else if (userInput == 5){
        diceRoll5 = userInput;
        numUserIns++;
        numFives++;
    } else if (userInput == 6){
        diceRoll6 = userInput;
        numUserIns++;
        numSix++;
    } else if (userInput < 1 || userInput > 6){
        cout << "invalid input";
        break;
    }
}
