 Reporter:  denis@…          |       Owner:  jofaber
     Type:  Bugs             |      Status:  new    
Milestone:  Boost 1.47.0     |   Component:  ICL    
  Version:  Boost 1.46.1     |    Severity:  Problem
 Keywords:                   |  
-----------------------------+----------------------------------------------
 here is the test case, reproducible with boost 1.46.1 and the today trunk.
 {{{
 #include <iostream>
 #include <assert.h>
 #include <boost/icl/interval_set.hpp>
 #include <boost/icl/interval_map.hpp>


 int main() {
   typedef boost::icl::interval_map<int, boost::icl::interval_set<int>> I1;
   I1 i(std::make_pair(0, 100)),
      j(std::make_pair(0, 200));
   std::cout << i     << std::endl; //  {([0,0]->{[100,100]})}
   std::cout << j     << std::endl; //  {([0,0]->{[200,200]})}
   std::cout << (i+j) << std::endl; //  {([0,0]->{[100,100][200,200]})}
   std::cout << (i-j) << std::endl; //  {([0,0]->{[100,100]})}
   std::cout << (i&j) << std::endl; //  {}
   assert((i&j).empty());

   // suppose to work same way as the test above
   typedef boost::icl::interval_map<int, boost::icl::interval_map<int,
 int>> I2;
   I2 k(std::make_pair(0, std::make_pair(100, 1))),
      l(std::make_pair(0, std::make_pair(200, 1)));
   std::cout << k     << std::endl; //  {([0,0]->{([100,100]->1)})}
   std::cout << l     << std::endl; //  {([0,0]->{([200,200]->1)})}
   std::cout << (k+l) << std::endl; //
 {([0,0]->{([100,100]->1)([200,200]->1)})}
   std::cout << (k-l) << std::endl; //  {([0,0]->{([100,100]->1)})}
   std::cout << (k&l) << std::endl; //
 {([0,0]->{([100,100]->1)([200,200]->1)})} while expecting {}
   assert((k&l).empty());
 }
