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
