The Wiinstrument

The application tends to crash every second minute or so (but can sometimes
run 10 minutes or more at once, albeit also but 5-10 seconds at times),
leaving the following trail in stdout:
[CODE]wiinstrument: ./boost/circular_buffer/details.hpp:285: typename
boost::iterator<std::random_access_iterator_tag, typename
Traits::value_type, typename Traits::difference_type, typename
Traits::pointer, typename Traits::reference>::reference
boost::cb_details::iterator<Buff, Traits>::operator*() const [with Buff =
boost::circular_buffer<double, std::allocator<double> >, Traits =
boost::cb_details::nonconst_traits<std::allocator<double> >]: Assertion
`is_valid(m_buff)' failed.
