Comment (by jhunold):

 the last patches broke some of my code which uses lexical_cast
 to parse values from std::vector<char>

 Something as simple as

     std::vector<char> buffer;
     return boost::lexical_cast<int>(&buffer[0]);

 fails with

 BOOST_ROOT/boost/lexical_cast.hpp:1091:43: error: no matching constructor
 for
 initialization of 'std::basic_ostream<char>'
                 std::basic_ostream<CharT> stream(&stringbuffer);
                                           ^      ~~~~~~~~~~~~~
 this is the start of the clang diagnostic.

 Both gcc (Ubuntu 4.6.0-3~ppa1) 4.6.1 20110409 (prerelease)
 and clang version 3.0 (trunk 135897)

 output contained in attached testcase lex.tar.gz
