9227,boost::regex match_count off by 1,spoo@…,John Maddock,"{{{
#include <boost/regex.hpp>

int main(int, char **)
{
	boost::regex r(""(a)"");
	std::cout << r.mark_count(); 
	return 0;
}
}}}

prints out ""2"" instead of ""1"".  Both libc++ and libstdc++ print out ""1"".  

This was discussed in 2007 as well I believe, but I couldn't find any other mention of the issue: [regex] regex::mark_count() incorrect? (I can't post the link since trac rejects my submission)",Bugs,closed,To Be Determined,regex,Boost 1.54.0,Problem,fixed,,
