Hi Gennadyi ! Nice to see you back ! Could you please take a look at issue #2390 again ? https://svn.boost.org/trac/boost/ticket/2390 There are currently two patches missing: - attached patch to make operator() of check_is_small and check_is_close "const". This is needed because Boost.Test now stores "const&" due those two objects due to the previous applied ODR-patch. - gcc-4.3 warnings "../boost/test/floating_point_comparison.hpp:88: warning: suggest parentheses around && within ||" which are rather annyoing.
