I am honestly curious to see examples of incorrect code that somehow manages to work as intended when not optimized, and fails when optimized. Maybe it exists, but it's not something I've come across.

Thomas here was pretty clear. He is not ruling out that programmers make errors. Rather than it is difficult (impossible?) to see errors fixed by the optimizer.

If you optimize an "error", I would presume that it is even harder to spot it, if the error is subtle.
