Шаблон std::allocator класса по умолчанию Allocator используется всеми стандартными контейнерами библиотеки, если не указанное пользователем распределителя обеспечивается. По умолчанию распределитель является лицом без гражданства, то есть, все экземпляры данного распределителя являются взаимозаменяемыми, сравнить равные и может освободить память, выделенную любой другой экземпляр того же типа распределителя.

Original:

The std::allocator class template is the default Allocator used by all standard library containers if no user-specified allocator is provided. The default allocator is stateless, that is, all instances of the given allocator are interchangeable, compare equal and can deallocate memory allocated by any other instance of the same allocator type.

Специализация для void не хватает члена ЬурейеЕ reference, const_reference, size_type и difference_type. Эта специализация не объявляет функций-членов.

Original:

Specialization for void lacks the member typedefs reference, const_reference, size_type and difference_type. This specialization declares no member functions.

All custom allocators also must be stateless.	(до C++11)
Custom allocators may contain state. Each container or another allocator-aware object stores an instance of the supplied allocator and controls allocator replacement through std::allocator_traits.	(начиная с C++11)
