6c966bba59 Fix incorrect (off by one) bound check. Also assert that we don't 
increment ``m_num_segments`` beyond the maximum value
(``c_max_segments``).

This is related to #436.

When doing an AddressSanitized build and running the ``c_example``
it looks like Z3 tries to create too many segments and index out of
bounds. Fixing the checks here causes them to fail which should help
us narrow down the problem.
