--------------------+-------------------------------------------------------
 I'm under OS X 10.8.4.
 The situation is the following:
 - An mlpack library built with g++ 4.8.
 - A very simple program compiled with g++ 4.8 :

 {{{
 #include <gmm.hpp>
 #include <iostream>

 void main()
 {
   std::cout << "Hello World" << std::endl;
 }
 }}}

 - With the following compilation line:

 {{{
 /opt/local/bin/g++-mp-4.8 -std=c++11 src/main.cc
 -I/usr/local/include/mlpack -I/usr/local/include/mlpack/methods/gmm
 -I/opt/local/include/libxml2 -L/usr/local/lib -L/opt/local/lib -lmlpack
 -larmadillo -o explore
 }}}

 The problem is the following:
 - It compiles with no error and produces the following output at execution
 :

 {{{
 bus error  ./explore
 }}}


 - Using a debugger on this gives the following :

 {{{
 $> lldb ./explore
 Current executable set to './explore' (x86_64).
