----------------------------------+-----------------------------------------
 The following simple program fires a stack overflow exception in
 xpressive. It's seems too simple to be causing such problems.

 {{{#include "stdafx.h"
 #include <string>
 #include <boost/xpressive/xpressive.hpp>
 using namespace boost::xpressive;


 int _tmain(int argc, _TCHAR* argv[])
 {
         sregex rx = ~(set='{', '}', ',');
         sregex rx2 = +rx;

         std::string s(10000, 'a');
         regex_search(s, rx2);

         return 0;
 }}}}

 I'm using MSVC 2005. The problem only occurs if the string is large.
