In my code I'm using BOOST_RANDOM_DETAIL_SEED_SEQ_SEED(my_engine, SeeqSeq, seq) { ... sizeof(typename SeeqSeq::result_type) and the script test my code with SeeqSeq = boost::random::test::seed_seq_archetype > This seed_seq_archetype defined in random/test/concepts.hpp seems to be missing result_type. It has value_type instead. The C++11 draft (N3242 p905) says it should have a result_type and that's also what I see in boost/random/seed_seq.hpp" Bugs closed To Be Determined random Boost 1.55.0 Problem wontfix
