 Using Xpressive with dynamic regexes.

 If a ':' appears two times in a search pattern expression the programm
 will crash.

 One ':' must be at the very beginning the other at the end of the
 expression.

 This may hold true for other cases, however not tested yet.

 #include <string>
 #include <iostream>
 #include <boost/xpressive/xpressive.hpp>

 using namespace std;
 using namespace boost;
 using namespace boost::xpressive;

 int main()
 {
         sregex rex = sregex::compile( "[:digit:]" );

         return 0;
 }
