To get a pure python-debug build you need to explicitly tell boost to
link to the debug version of python, by passing the option
python-debugging=on to bjam when building boost. You will ghen get
boost_python-vc80-mt-gyd-1_35.lib and .dll instead, and need to link
to that.

You also need to define BOOST_DEBUG_PYTHON when you build your
application, see this url:
http://www.boost.org/doc/libs/1_36_0/libs/python/doc/building.html#python-debugging-builds

Hope this helps!
