I have had nothing but troubles with boost test 1.34.1 after switched
from 1.33.  First I had trouble with the main from shared object issue,
and now my code that worked before is not executing a test added to the
framework.
#include <iostream>
#define BOOST_TEST_DYN_LINK
#define BOOST_TEST_MAIN
#define BOOST_TEST_MODULE File Test
#include 
#include 
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;
   }
};
BOOST_AUTO_TEST_CASE( test123 )
{
    boost::shared_ptr tester(new my_test<int>);
boost::unit_test::framework::master_test_suite().add(BOOST_TEST_CASE(boost::bind(&my_test<int>::execute,
tester, 5)));
}
This is incorrect way to register test units.
...
this worked when it was not using boost::bind but just the address of a
normal function. This is just an simple version that illustrated the
problem.  I am compiling as such
g++ test.cpp -o test -L/usr/local/lib -lboost_unit_test_framework-gcc41-mt
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 
#include 

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 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 

typedef boost::mpl::list 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;
}
