This ignores the exception specifications of default constructors for base classes and nonstatic data members and of functions called in brace-or-equals-initializers of nonstatic data members.
Proposed resolution (August, 2011):

Change _N4527_.12.9 [class.inhctor] paragraph 3 as follows:

Change 14.5 [except.spec] paragraph 14 as follows:
An implicitly declared special member function ( 11.4.4 [special]) shall have an exception-specification. If f is an implicitly declared default constructor, copy constructor, move constructor, destructor, copy assignment operator, or move assignment operator, its implicit exception-specification specifies the type-id T if and only if T is allowed by the exception-specification of a function directly invoked by f's implicit definition; f shall allow all exceptions if any function it directly invokes allows all exceptions, and f shall allow no exceptions if every function it directly invokes allows no exceptions.
