Assuming (b) is the correct interpretation of Question 1, if a particular implementation expands offsetof into an expression which contains operands and/or operators which result in a violation of the definition of “integral constant expression” from subclause 6.4, page 55, lines 17-21, does this situation constitute:

a. a constraint violation since the expansion presented for further translation is not an “integer constant expression?”

or

b. undefined behavior since the definition of “integral constant expression” appears in a “shall” requirement in the semantic description of subclause 6.4 Constant expressions?

Response

The response to Question 1 makes this a moot question.
