buffered_channel failed to compile with g++ 4.8 on Ubuntu

[sdeber]

I am trying to compile the code example with g++4.8 on Ubuntu 14.04 in the tutorial from boost website
http://www.boost.org/doc/libs/1_63_0/libs/fiber/doc/html/fiber/synchronization/channels/buffered_channel.html

And it failed with the following error:

opt/third_party/include/boost/fiber/buffered_channel.hpp: In instantiation of ‘boost::fibers::buffered_channel::buffered_channel(std::size_t) [with T = HAUD::SS7Wrapper*; std::size_t = long unsigned int]’:

Any ideas?

it's a compiler problem - AFAIK gcc-4.8 is not fully C++11 compliant
