hi all, i just figured out, that the problem, that was discussed in this thread: http://lists.boost.org/Archives/boost/2003/02/44916.php somehow hasn't been fixed ... i've attached a small regression test, showing the problem ... the fix is rather trivial, though: --- boost/random/lognormal_distribution.hpp (revision 681) +++ boost/random/lognormal_distribution.hpp (working copy) @@ -60,8 +60,8 @@ // compiler-generated copy ctor and assignment operator are fine - RealType& mean() const { return _mean; } - RealType& sigma() const { return _sigma; } + RealType mean() const { return _mean; } + RealType sigma() const { return _sigma; } void reset() { _normal.reset(); } template<class Engine> would be great to see this fixed ... cheers, tim -- tim@klingt.org ICQ: 96771783 http://tim.klingt.org The aim of education is the knowledge, not of facts, but of values William S.
