I'm well aware of what undefined behavior is. I still know it's undefined behavior and can read my compiler manual to answer the question of how the code behaves. "I don't know" is simply wrong.

Which is both not true (because the compiler manual usually won't define undefined behaviour) and irrelevant (because the questions were about C, not about a compiler).
In the example I choose (#2) most compilers totally specify the behavior. And the question was (right from the article) "what the return value would be?" In order for a function to return, it must be run. In order for a function to be run, it must be compiled. In order for a function to be compiled, there must be a compiler (or interpreter, I suppose).
You're being pedantic about something silly, but you're also wrong in your pedantry.
