Hi,

the last patches to lexical_cast 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.

Btw. are there any lexical tests in Boost?

Yours,

Jürgen
