It's what happens when a program steps outside its computational model — and the compiler, a perfect executor, follows the math.

Undefined Behavior isn't compiler magic or a flaw in the standard. It's what happens when your program steps outside its computational model. The compiler trusts you to stay inside it. When you don't — there's no correct answer. Mathematically.
