            Bug ID: 19053
           Summary: clang can treat a dynamic POD variable as an array
                    without warning/error
           Product: clang
           Version: unspecified
          Hardware: All
                OS: All

Hello guys, we had at university this issue: compiling the code below, throws
no error messages whatsoever, but the code is, as you know, not working. It's,
at least for me, that compiler would recognize this type of mistakes and so it
would be kinda nice to have some type checking upon POD types.

The code is:

int main()
{ 
   int* pod_type = new int(23);

   for (int i = 0; i < 10000; i++)
     pot_type[i] = 0xDEADC0DE;

   delete pod_type; 
   return 0;
}

Thank you. (this bug has been already pushed to g++ bugtracker by me).
