In my experience, "not what the coder expected." The pattern is less obvious when it's a result of aliasing. But if I see it happening, I just assume undefined behavior, and try to figure out what the intent was so I can rewrite.
This is my answer to quizzes about operator precedence too: "if you have to ask, you need more parens." :-)
