It is correct that compile errors may arise. The easiest fix is to define in 
exception.hpp

#define BOOST_UBLAS_SAME(size1, size2) same_impl_ex<std::size_t> ((size1), 
(size2), __FILE__, __LINE__)

and still use unbounded_array<int> as index_array_type.

Clearly, this issue is important and requires some discussion (which I opened 
a while ago).
