Have you thought about why having a standard causes all these problems with undefined behavior? The point of a standard is to be less specific than a reference implementation. That's why it's written in English, not code. That means definitions are fuzzy, which is why every kind of English-language law, rule, or spec is vulnerable to malicious compliance.

If C had a judge, like the legal system, he could deny attempts to use fuzziness in the standard (intended to prevent specifying bugs) to introduce bugs. Unfortunately, C doesn't have a judge with common sense, it has people who think the standard is code and anything that is undefined really is a license to do whatever you want.

I guess this problem was inevitable as soon as the words "nasal demons" were put to keyboard. Now the only thing that can save us is a reference implementation.
