Boost C++ Libraries: Ticket #2752: Wrong size check in bounded_array::resize

Steven Watanabe — Thu, 12 Feb 2009 17:35:19 GMT

How can the size be larger than N?

It should be okay to set the size equal to N, because there is storage for N elements, right? If size is greater than N, then it will be caught by the BOOST_UBLAS_CHECK.

What am I missing?

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.
