You will see that if you have disabled exception handling in your project:
in that case the lib doesn't know what to do when it needs to throw - so you
need to provide your own error handler - see
boost/detail/throw_exception.hpp for the signature - or turn on compiler
exception support if you hadn't realised it was off :-)
