virtual void* do_allocate( std::size_t bytes, std::size_t alignment ) = 0;		(library fundamentals TS)

Allocates storage with a size of at least bytes bytes. The returned storage is aligned to the specified alignment if such alignment is supported, and to alignof(std::max_align_t) otherwise.

alignment shall be a power of two.

Exceptions

Throws an exception if storage of the requested size and alignment cannot be obtained.
