2887,mersenne_twister generated copy ctor overloaded by a template ctor,corlay@…,No-Maintainer,"Compiled-generated copy constructor and assignment operator are fine, but the copy constructor is overloaded by mersenne_twister(Generator & gen) { seed(gen); } even is the Generator type is mersenne_twister;

{{{
  template<class Generator>
  explicit mersenne_twister(Generator & gen) { seed(gen); }

  // compiler-generated copy ctor and assignment operator are fine
}}}

Hence calling
{{{
	boost::mt19937 rng(0);
	boost::mt19937 rngcopy(rng);
        std::cout << (rng==rngcopy) << std::endl;
}}}
yields ""false"". 

Maybe a boost::disable_if<boost::is_same<mersenne_twister,Generator> > solves the problem.

See also the workaround  made in default constructor of 
boost::pass_through_engine to avoid matching Generator & constructor
