671,"regex_match fails, but regex_search works fine",nobody,John Maddock,"{{{
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.
