Yes you are right I'm using the std coming with my gcc 4.9.2:  g++ (Ubuntu 4.9.2-0ubuntu1~14.04) 4.9.2

And I'm sorry to have stated that with BOOST_SP_USE_STD_ATOMIC still the issue is there, but it doesn't seems so,
I believe in my earlier test I copied/pasted not the complete macro.

So just to sum up:

boost based version:  
    http://pastebin.com/zh0SPz5n                           WARNING
    http://pastebin.com/zh0SPz5n + BOOST_SP_USE_STD_ATOMIC OK
    http://pastebin.com/zh0SPz5n + BOOST_SP_USE_PTHREADS   OK

std based version (std from gcc 4.9.2):
    http://pastebin.com/X6u1rD0c                           OK
