Allocate a buffer of memory having the specified `size` (in bytes), and alignment defined by `bsls::AlignmentUtil::BSLS_MAX_ALIGNMENT`, from virtual memory. If `size` is 0, return a null pointer with no other effect. If this allocator cannot return the requested number of bytes, then it will throw a `std::bad_alloc` exception in an exception‐enabled build, or else will abort the program in a non‐ exception build. The behavior is undefined unless `0 <= size`.
