[Moved to DR at the April, 2013 meeting.]
Proposed resolution (February, 2012):
Change 11.4 [class.mem] paragraph 20 as follows:
A pointer to a standard-layout struct object, suitably converted using a reinterpret_cast, points to its initial member (or if that member is a bit-field, then to the unit in which it resides) and vice versa.[Note:...
According to 11.4 [class.mem] paragraph 20,
A pointer to a standard-layout struct object, suitably converted using a reinterpret_cast, points to its initial member (or if that member is a bit-field, then to the unit in which it resides) and vice versa.
Given a standard-layout struct in which the non-static data members are in a base class (and hence the derived class is empty), it is not clear what the “initial member” is. Presumably the intent behind allowing such standard-layout classes was to treat the base class object and its first non-static data member as the initial member of the derived class, but this does not appear to be spelled out anywhere.
