John: This article (https://kamchihau.blogspot.com/2022/12/httpskamchihau_24.html) mention about how the point of gap-checking work in integrated circuit.

.

Me: Fine.

.

John: This article (https://kamchihau.blogspot.com/2024/08/blog-post.html)  say that stack-Overflow isn't the principles of hacking, because, the clock line doesn't cover the area of stack-overflow, .

.

.

Me: OK. Let me explain the above picture. There're register 1, area of overflow, register 3.

.

John: OK. 

.

Me: There's a gap between register 1 and the area of stack over-flow.

.

John: OK.

.

Me: If register 1 stack over-flow, the consequence is that

the field of the value of register 1 expand.

The field of the value of register 1 expand to the area of over-flow.

.

The gap between register 1 and the area of over-flow disappear. 

.

Consequently, new register can't appear after register 1. 

.

(a new register can't appear between register 1 and register 3) 

.

Because, 

there is no more gap between register 1 and new register.

.

John: The principles of hacking isn't "Stack overflow".

.

Me: Stack over-flow just result in the gap disappearing between registers.

.

John: Correct.
