Summary: regex_match fails, but regex_search works fine

Initial Comment:
I encountered this when I tried to upgrade from 1.32
to 1.33.1

I search through a text with regex_search, and pass
the results to regex_match. I would expect them to
yield the same result, but they don't.

Here is a sample code:

        std::string pattern = "xx-{0,2}([+-][0-9])?";
        boost::regex reg(pattern.begin(), pattern.end
(), boost::regex::perl_syntax_group );

        char* buf = "xx-- ";
        boost::cmatch what;

        regex_search(buf,what,reg,
boost::regex_constants::match_default);
        bool match = regex_match(what[0].first, what
[0].second,reg, boost::regex_constants::match_any);

regex_search returns the [0,4), as I expected, but
regex_match returns false!

Am I doing something wrong? Is there a workaround?

Thanks, Moddy.
