  • Ticket #8438 – Description

    initial v3  
    11When compiling the following code without optimizations, it behaves as expected: (compiled with g++-4.7.2 with no flags at all)
    22
     3
     4{{{
    35#include <boost/numeric/ublas/vector.hpp>
    46#include <boost/numeric/ublas/io.hpp>
    … …  
    1315    return 0;
    1416}
     17}}}

    1721Output:

     23{{{
    1824[3](1,1,1)
    1925[3](1,5,1)
    20265

    2230When compiling the exact same code with O1, O2, and O3 it produces the following output:
     31
     32{{{
    2333[3](0,0,0)
    2434[3](0,0,0)
    25355
     36}}}
     37

    2739I noticed that inner_prod() also sees the vector as zeros.
