[boost] [circular_buffer] default constructor usually throws std::bad_alloc

I've attached a trivial patch to circular buffer which should allow it
to be default constructed (and copy from an existing buffer) without
making the default constructor cause an insane request to allocate a
huge amount of memory (and fail to throw an std::bad_alloc).

I personally think this is a show stopper bug in Boost 1.35.0 and the
patch is distributed under the Boost C++ License Version 1.0. Should
this be applied to be made part of 1.35.1?
