Comment (by anonymous):

 Ah-ha!  I did some further testing.\
 Though all the messages point to the line declaring the circular_buffer,
 the warnings only appear when the !TestSetupContainer struct's ctor
 contains this line:

 {{{
 output_buffer_.resize(10);
 }}}

 So it would appear that the call to "resize" actually triggers the
 warnings.\\
 I commented out everything in that test file except that struct
 declaration (and necessary #includes), just to be sure.

 I also changed the declaration of "output_buffer_" to these types:\\
 ||="output_buffer_" type||result=||
 ||boost::circular_buffer<int>||NO warning||
 ||boost::circular_buffer<boost::shared_ptr<int>>||SAME warning||
 ||boost::circular_buffer<std::shared_ptr<int>>||SAME warning||

 If I think of anything else, I'll post more here.
