[boost] [format] Bug: empty first argument -> crash

MSVC 8, SP1, boost 1.33.1:

<snip>
#include <iostream>
#include <ostream>
#include <istream>
#include <boost/format.hpp>

int main()
{
   std::cout << boost::format("empty: %1%") % "";  //crash
   std::cin.ignore();
   return 0;
}
<snip>

I consider this a showstopper bug.

Best regards
