The execution path has unknown side effects, and so the execution path must be strictly followed. That's uh... The entire point of that section in the C standard. Its why volatile is called out, in the semantic model for the abstract machine.

Otherwise... Why call it out, at all? It must be strictly followed, not lazily, as in other areas of the standard.

> The initialization shall occur in initializer list order, each initializer provided for a particular subobject overriding any previously listed initializer for the same subobject

And what I am trying to tell people, is the standard has expectations around the volatile keyword, that the compilers took into account when designing how they would work - it isn't just kindness, its compliance. But no one is actually talking about the quotes from the standard, and just quoting themselves and their own understandings.
