     Type:  Bugs          |      Status:  new         
Milestone:  Boost 1.49.0  |   Component:  lexical_cast
  Version:  Boost 1.48.0  |    Severity:  Regression  
 Keywords:                |  
--------------------------+-------------------------------------------------
 The following code works with 1.46.1 but fails with a `bad_lexical_cast`
 exception on 1.48.

 {{{#!cpp
 #include <string>
 #include <iostream>
 #include <boost/lexical_cast.hpp>

 struct my_string
 {
         friend std::ostream &operator<<(std::ostream& sout, my_string
 const& st)
         {
                 return sout << "";
         }
 };

 int main()
 {
         try
         {
                 my_string st;
                 std::string st2 = boost::lexical_cast<std::string>(st);
         }
         catch(boost::bad_lexical_cast const &e)
         {
                 std::cout << e.what() << std::endl;
         }
 }
 }}}
