 Hi,
 Just found a problem with regex when upgrading to boost 1.44.0. Seems like
 regex_match can return true and match_results contain the correct number
 of entries, but they are all empty.

 I downloaded and compiled 1.44.0 on Ubuntu 8.04 using gcc 4.1.3 using the
 following cmd: ./bootstrap.sh --with-libraries=serialization,regex
 --includedir=/usr/include --libdir=/usr/lib; bjam

 Attached is a small testcase extracted from our code base, which gives the
 following result when compiled and executed:

 4 >< >< ><
 terminate called after throwing an instance of
 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::bad_lexical_cast>
 >'
   what():  bad lexical cast: source type value could not be interpreted as
 target
 Aborted

 Thanks and regards
 Jannich
