Hi,

Thanks for the info. This was already fixed in dev branch so I've merged 
the code. Please check it out. There is a lot of changes related to 
exception-safety. As usual:

http://svn.boost.org/svn/boost/sandbox-branches/geometry/index/

Unfortunately the interface was slightly changed. Methods and functions 
names:
- query() was changed to spatial_query(),
- nearest() to nearest_query(),
- corresponding filters names was also changed, now they're in 
'adaptors' namespace.
Please see the docs.

If you have any suggestions, let me know.

Regards,
Adam
