Milestone:  To Be Determined           |   Component:  random       
  Version:  Boost 1.47.0               |    Severity:  Problem

---------------------------------------+------------------------------------
 The following code, compiled on my mac (i686-apple-darwin9-g++-4.2.1) goes
 into an infinite loop.
 The problem is in  boost::uniform_real<double>(90,90)(rng); as the lower
 and upper bounds are the same

 #include<boost/random/uniform_real.hpp>


 #include<boost/random/lagged_fibonacci.hpp>


 #include<iostream>



 int main() {


 boost::lagged_fibonacci607 rng(32);


 double r = boost::uniform_real<double>(90,91)(rng);
 std::cout << r << std::endl;




 r = boost::uniform_real<double>(90,90)(rng);


 return 0;


 }
