[Moved to DR at the April, 2013 meeting.]
Proposed resolution (October, 2012):
Add the following as a new paragraph before 7.6.6 [expr.add] paragraph 7:
For addition or subtraction, if the expressions P or Q have type “pointer to cv T", where T is different from the cv-unqualified array element type, the behavior is undefined. [Note: In particular, a pointer to a base class cannot be used for pointer arithmetic when the array contains objects of a derived class type. —end note]
If the value 0 is added to or subtracted...
The current wording is not sufficiently clear that a pointer to a base class subobject of an array element cannot be used in pointer arithmetic.
