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?
