Hi all, considering that BOOST 1.60 changes the ABI when compiled with -std >= c++11 versus -std <= c++03 (cf. [1]) , and that g++-6 defaults to -std=c++14 it would probably be a good idea if a boost >= 1.60 version compiled with g++6 would be available from experimental when the bug squashing starts.
