Milestone:  To Be Determined  |  Component:  regex

 {{{
 #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)
