With these it helps You cannot use pointer arithmetic on pointers that point at separate arrays. a and b are two different arrays.

Heap / buffer overflow exception

This might help you Just curious, Is there or has anyone ever come across a heap / buffer overflow exception in C#? , You can cause a buffer overflow in C# in unsafe code. For example:
code :
public unsafe struct testo
{
    public int before;
    public fixed int items[16];
    public int after;
}

testo x = new testo();
x.after = 1;
for (int i = 0; i <= 16; ++i)
{
    unsafe
    {
        x.items[i] = 99;
     }
}
Console.WriteLine(x.after);

Stack overflow with heap buffer?

fixed the issue. Will look into that further As Matthieu said, Box::new([0; 1024 * 1024]) will currently overflow the stack due to initial stack allocation. If you are using Rust Nightly, the box_syntax feature will allow it to run without issues:
code :
#![feature(box_syntax)]

fn main() {
    let mut buf: Box<[u8]> = box [0; 1024 * 1024]; // note box instead of Box::new()

    println!("{}", buf[0]);
}

C programming heap buffer overflow

hop of those help? I just started coding and have a beginner question. So I have a Binary tree. After I add the first node to it, I would like to search the tree see if there are any duplicated node with the same value. But I keep getting error when I try to search the tree which has only one node: Here is my node:
code :
struct node *p = malloc(sizeof(struct node*));
struct node *p = malloc(sizeof(struct node));
struct node *p = malloc(sizeof(*p));

heap-buffer-overflow on address

it helps some times Learn to use a debugger.
Your problem is that after the first run through the loop, the input is [3, 0, -3]. When you process the final element, you try and access element -4, which is never going to end well.
