[pkg-boost-devel] Bug#538946: Known problem, still present in 1.40

[Steve M. Robbins]

Hi,

Just wanted to record that this problem has been known for some time
[1].  At the end of that thread, Peter Klotz provides a solution
similar to yours.  It appears not to have been fixed because the
upstream developer does not believe Boost.Test code is faulty.

Also, the bug still exists in 1.40.  The demonstration is simple:

steve at riemann{boost}cat boost-test-auto-main.cc                                                             
#define BOOST_AUTO_TEST_MAIN                                                                                
#include <boost/test/auto_unit_test.hpp>                                                                    

BOOST_AUTO_TEST_CASE( dummy )
{                            
    BOOST_ASSERT(1);         
}
