Segmentation fault in boost::odeint my_vector.cpp example - c++11

Question

I am trying to test the my_vector.cpp program from boost::odeint examples but without any success. I get Segmentation Fault when I run the program.
Compilation: g++ -std=c++14 -o my_vector my_vector.cpp
It runs with std::vector<> instead of my_vector for the state_type. I suspect there is something wrong with is_resizable but I don't know how to fix it.
Here is the code for my_vector.cpp which you can get from github

Answer 1

I can reproduce this with g++-4.8.
I've opened an issue on this at the odeint github repository:
https://github.com/headmyshoulder/odeint-v2/issues/180
edit:
I've found the problem and solved it: https://github.com/headmyshoulder/odeint-v2/commit/965a8e456d5e9dff47f0121a4d12aac8c845ea5e
The problem was an inconsistent template parameter type that prevented the is_resizeable definition to work properly, as expected by the op already.
changing the my_ vector template parameter type to size_t fixes this:
template<size_t N>
class my_vector
