It appears there is only malloc allocation available in AutoBuffer now, not
the in-object allocation I use. While I'm trying to maintain the simplicity
of boost.array with size tracking, that may not be others' goal. I would be
happy to try adding the allocation style of StaticVector as an additional
allocator in AutoBuffer. Unfortunately, I am not sure how I could add the
functionality I'm looking for to AutoBuffer myself. Is there a resource I
could use to learn what I need to allocate the memory block inside the
AutoBuffer object itself without pointers to externally allocated memory? It
would be greatly appreciated.

I happen to be using it in an embedded environment myself, but I can use
exceptions. Is there some good example code somewhere that I can use as a
style guide for implementing a no exceptions option?
