Addresses GB-68
There is no reason for the offsetof macro to invoke potentially throwing operations, so the result of noexcept(offsetof(type,member-designator)) should be true.
[ Resolved in Rapperswil by a motion to directly apply the words from the ballot comment in N3102. ]
Proposed resolution:
Add to the end of 18.2p4:
No operation invoked by the offsetof macro shall throw an exception, and
noexcept(offsetof(type,member-designator))shall be true.
