There are inconsistent definitions for allocator_arg. In 20.2 [memory] paragraph 1,

constexpr allocator_arg_t allocator_arg = allocator_arg_t();

and in 20.9.1,

const allocator_arg_t allocator_arg = allocator_arg_t();

[ Resolved in Rapperswil by a motion to directly apply the words from the ballot comment in N3102. ]

Proposed resolution:

Change "const" to "constexpr" in 20.9.1 as follows.

constexpr allocator_arg_t allocator_arg = allocator_arg_t();
