It might, but it doesn't, and much of it says about this issue is wrong. Compare what it says in 2.2 with C11 6.5.2.1 paragraph 2.

"Equivalence" refers to the following key definition:

An lvalue [see question 2.5] of type array-of-T which appears in an expression decays (with three exceptions) into a pointer to its first element; the type of the resultant pointer is pointer-to-T. (The exceptions are when the array is the operand of a sizeof or & operator, or is a literal string initializer for a character array.)

No, that's not relevant to this issue. That refers to C11 6.3.2.1, but the relevant section is 6.7.6.3.

In this case, we're passing the argument to operator &, which disables the automatic decay.

That would make the effects entirely different. Sorry, but that's irrelevant to this case. Regards, Nick Maclaren.
