Comment(by Ulf Olin <ulf.olin_at_[hidden]>):

 Say that you have have created a bounded_array with three elements (N=3
 and size_=3). Then you, by mistake, try to resize that bounded_array to
 hold four elements. That is, your code is

 {{{
 #include <boost/numeric/ublas/storage.hpp>

 int main () {
     using namespace boost::numeric::ublas;
     bounded_array<double, 3> a (3);
     a.resize(4); // Should result in an exception, but it doesn't!
 }
 }}}

 The solution for the definition of the resize function is either to check
 the function argument, size, instead of the member size_, or to first do
 the assignment statement and then the check.
