Proposed resolution (February, 2012):

This issue is resolved by the resolution of issue 616.

Date: 2009-12-10.00:00:00

According to 7.3.2 [conv.lval] paragraph 1, an lvalue-to-rvalue conversion on an uninitialized object produces undefined behavior. Since there is only one “value” of type std::nullptr_t, an lvalue-to-rvalue conversion on a std::nullptr_t glvalue does not need to fetch the value from storage. Is there any need for undefined behavior in this case?
