#7871: [ICL][c++11] split_interval_map: move-assignment removes implicit copy-
assignment
------------------------------+---------------------------------------------
 Reporter:  opium             |       Owner:  jofaber
     Type:  Feature Requests  |      Status:  new    
Milestone:  To Be Determined  |   Component:  ICL    
  Version:  Boost 1.52.0      |    Severity:  Problem
 Keywords:                    |  
------------------------------+---------------------------------------------
 split_interval_map has no explicit copy-assignment operator, so using
 copy-assignment with c++11 causes compilation error:

 {{{
 #include <boost/icl/split_interval_map.hpp>

 int main ()
 {
   boost::icl::split_interval_map <int, int> A, B;
   A = B;
   return 0;
 }
 }}}

 Compilation error:
 {{{
 test.cpp: In function 'int main()':
 test.cpp:7:7: error: use of deleted function
 'boost::icl::split_interval_map<int, int>&
 boost::icl::split_interval_map<int, int>::operator=(const
 boost::icl::split_interval_map<int, int>&)'
 In file included from test.cpp:2:0:
 /home/opium/dev_libs/boost_1_52_0/include/boost-
 1_52/boost/icl/split_interval_map.hpp:33:7: note:
 'boost::icl::split_interval_map<int, int>&
 boost::icl::split_interval_map<int, int>::operator=(const
 boost::icl::split_interval_map<int, int>&)' is implicitly declared as
 deleted because 'boost::icl::split_interval_map<int, int>' declares a move
 constructor or move assignment operator
