This is how I discovered that one of my code was "bugged". I had to implement a driver for an obscure chinese-made machine with a documentation google translated. In the protocol, there was a check byte and the explanation says that it was the 100 modulo of the sum of all previous byte. They didn't mention overflow. I tested it using a release build and it was working. Later on, while changing a few thing, I notice that the debug build was not working. I quickly find that this was because of the overflow behavior.
