     Type:  Bugs                     |      Status:  new    
Milestone:  To Be Determined         |   Component:  assign 
  Version:  Boost Development Trunk  |    Severity:  Problem
 Keywords:                           |  
-------------------------------------+--------------------------------------
 The problem is due to the addition of rvalue-reference container
 constructors. The following fails to compile with vc10:

 {{{
 #include <vector>
 #include <boost/assign/list_of.hpp>

 int main()
 {
     std::vector<int> i(boost::assign::list_of(1));
 }
 }}}

 The error is:

 {{{
