Help me runtime debug this code

Hey there… This happens to me sometimes. I want to be able to turn on a debug mode or a tool that will crash my code during runtime. I can use Xcode, MSVC 2008, or GCC under Linux. Anything. Though, XCode is preferred. This must work with C++, not just C code.

// I don't want to change my code.  I don't want to use Array templates.
// I just want a debugging tool that will crash my code when I do 
// array out-of-bounds, even if they are "safe."  Here's my example.

struct Goods {
    int x[10];
    int y[10];
    int z[10];
};

int main(int argc, char *argv[]) {
    Goods data;
    
    int k = 11;
    for (int i=0; i<k; i++) { data.y[i] = 1; } // SHOULD ERROR ON i == 10

    int j = -1;
    for (int i=j; i<10; i++) { data.y[i] = 1; } // SHOULD ERROR ON i == -1
 
    return 0;
}

Changing my code, using STL, using “new”, using “malloc” are not options.

Help me!
