That's an gcc issue (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54086) which was fixed in 4.7. So I think, you have to update your gcc version:

sudo add-apt-repository -y ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install g++-4.8
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 50
export CC=gcc-4.8
export CXX=g++-4.8

rebuild mlpack (remove the build directory).
