4641	regex_match return true but match_results contain empty entries	jannich@…	John Maddock	"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
