Sorry, already discovered the problem. (I had searched for some time the problem a while ago and just found out now). It seems to be the >::type, that way I think it will evaluate is_base_and_derived even when not needed, turning it in a O(n^2) complexity. The mpl::not makes no sense either, and is faulting a typename before mpl::not if I was to use >::type. It is incredible I passed so much time to find this. -- Felipe Magno de Almeida Developer from synergy and Computer Science student from State University of Campinas(UNICAMP).
