This is now a known and reported bug in the compiler. The only workarounds are:

1. Remove the flags as you suggested. This is okay, but those flags are very useful at times, and you don't want to remove them from projects and after the bug is fixed go back and update them again!

2. Execute in release mode for testing until you really need the debugger symbols and then temporarily remove the flags.

I have opted for #2 so that when the fix comes out, but projects are not missing the flags. For more information see:

BTW, the code the that I had that had this problem was just this simple:

#include 
#include 

using namespace std;

int main() {
    string firstName;
    string lastName;
    int age;
    char gender;

    cout << "Enter First Name: " << endl;
    cin >> firstName;  // <----- error happens right here

    cout << "Enter Last Name: ";
    cin >> lastName;

    cout << "Enter age: ";
    cin >> age;

    cout << "Enter gender: (m or f) ";
    cin >> gender;

    cout << firstName << lastName << age << gender;

    return 0;
}
