The following program compiles for me:
#include <list>
#include <boost/xpressive/xpressive_dynamic.hpp>
int main()
{
std::list<boost::xpressive::sregex> rxs;
boost::xpressive::sregex rex =
boost::xpressive::sregex::compile("hello");
rxs.push_back(rex);
std::list<boost::xpressive::sregex>::iterator it;
for (it= rxs.begin(); it != rxs.end(); it++)
{
//do something
}
}
So I don't know what the problem could be. What compiler/std-library are
you using, and what version of boost?

I don't remember that bug. Can you send a link to the ticket or to the
mailing list discussion?
