This is incorrect way to register test units.

I am not sure how it worked before, but the correct way to implement this is 
to use init function

#include <iostream>
#define BOOST_TEST_DYN_LINK
#include <boost/bind.hpp>
#include <boost/test/unit_test.hpp>

template <typename Functor>
struct my_test
{
   void execute(int value)
   {
       //Never prints this message
       //Doesn't have to be a print, nothing gets here
       std::cerr << "Hi all" << std::endl << std::flush;
   }
};

bool init_function()
{
  boost::shared_ptr<my_test<int> > tester(new my_test<int>);

  boost::unit_test::framework::master_test_suite().add(
   BOOST_TEST_CASE(boost::bind(&my_test<int>::execute, tester, 5)));

  return true;
}

int
main( int argc, char* argv[] )
{
    return ::boost::unit_test::unit_test_main( &init_function, argc, argv );
}

P.S. Alternatively, if you are not that interrested in either template or 
runtime parameter, you can use one of the other automated tools. For 
example:

#include <iostream>
#define BOOST_TEST_DYN_LINK
#define BOOST_TEST_MODULE Your test
#include <boost/test/unit_test.hpp>

typedef boost::mpl::list<int,long,unsigned char> test_types;

BOOST_AUTO_TEST_CASE_TEMPLATE( test_case1, T, test_types )
{
  //Never prints this message
  //Doesn't have to be a print, nothing gets here
  std::cerr << "Hi all" << std::endl << std::flush;
}
