Is it possible to enable array bounds checking in g++?

Question

Is it possible to have g++ show an error when compiling the following file with some flag?

#include <iostream>
using namespace std;

int main()
{
   int arr[ 2 ];

   cout << arr[ 4 ] << endl;

   return 0;
}

I saw some things like gcc -Wall -O2 main.c which only works with C, not C++.

Answer 1

Not at compile time. You might be able to check that at runtime though.

For that take a look at: Runtime array bounds checking with g++
