-------------------------------------------+---------------------------
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".
