7550	Vector of variate generators cannot be populated	fenix.citizen@…	No-Maintainer	"As in the title, it is impossible to populate a vector of variate generators. I tried to combine Mersenne Twister with uniform_real distribution. The problem appears when using assignment operator. There is no problem when I try to populate STL list with the same objects. The same issue appears for fixed seed. I observed that simple assignment of one variate generator to another one is also impossible. Please find my code snippet below. 

{{{
	boost::mt19937 rng(static_cast<unsigned int>(time(0)));
	std::vector<boost::uniform_real<> > unifRealDistrVector;
	typedef boost::variate_generator<boost::mt19937&, boost::uniform_real<> > unifRealVarGen;

	std::vector<unifRealVarGen> unifRealVarGenVector;
	//std::list<unifRealVarGen> unifRealVarGenList;
	for (unsigned int iter = 0; iter < 6; iter++) {
		boost::uniform_real<> unifRealDistr(0.0, iter);
		unifRealVarGen varGen(rng, unifRealDistr);
		unifRealVarGenVector.push_back(varGen);
		//unifRealVarGenList.push_back(varGen);
	}
}}}

I use Cross G++ Compiler 4.6.3 on Ubuntu. I am still learning Boost.Random library. Please correct me if such an operation does not make much sense. Thanks in advance."	Bugs	closed	To Be Determined	random	Boost 1.48.0	Problem	invalid	vector, STL, variate generator
