Constructor accepting an allocator as a single parameter should be qualified as explicit.
namespace std { template <class Key, class T, class Compare = less<Key>, class Allocator = allocator<pair<const Key, T> > > class map { public: ... map(const Allocator&);
[ Resolved in Rapperswil by a motion to directly apply the words from the ballot comment in N3102. ]
Proposed resolution:
Add explicit.
namespace std { template <class Key, class T, class Compare = less<Key>, class Allocator = allocator<pair<const Key, T> > > class map { public: ... explicit map(const Allocator&);
