Nasos,
Hey this is embarrassing, I wrote your name very wrong in the last mail sorry lol... :/ ...don't know why I did that...
I have just talked with joel_falcou at the boost chat room, and he told me that I have cache issues. His point seem to be really true, then I'm going to work around the structure layout in memory. I'm pretty sure that is the problem now.
About that compilation error, even after some research and workaround attempts, I have no idea what that is about.
Thanks (and sorry) again.
