Heap on Mac and Linux

#include <iostream>

int main() {

   double *a = new double[5];
   for(auto i = 0; i < 5; i++)
     a[i] = i;

   std::cout << a[-10] << std::endl;


This program runs on Mac without warning or error. However, it gives segmentation fault (core dump) error on ubuntu and cent os.
