-------------------------------------------+---------------------------
 The copy constructor for mt19937_64 seems to leave the copy in a corrupt
 state.  Trying to generate random numbers from the copy consistently
 results in a segmentation fault.

 The attached file exhibits the problem:

 $ g++ -std=c++11 -g -O0 main.cpp && ./a.out
 5
 5
 $ g++ -std=c++11 -g -O0 -DUSE_64BIT main.cpp && ./a.out
 1
 Segmentation fault (core dumped)

 The version of g++ used is "g++-4.8 (Ubuntu 4.8.1-2ubuntu1~12.04) 4.8.1".
